The gasoline trimmer stalls when you press the gas

Stalls when tilted

The reason that the chainsaw starts to stall when tilted is the lack of flow of the fuel mixture into the system. The fuel pipe is located directly at the bottom of the gas tank, so tilting the tool causes the pipe to simply sit over the fuel mixture. Actually, therefore, during the operation of the tool, it can suddenly stall.

The chainsaw engine stalls when you press the gas

The chainsaw is a highly efficient tool for working with wood. However, the high-speed motor of this tool can be used for a variety of other tasks, which is achieved through special attachments. Sometimes a malfunction such as the chainsaw stalls when you press the gas, which can be triggered by some factors. In order not to have to disassemble the tool completely, we will consider all sorts of reasons for this problem with a detailed description of how to fix them.

When you hit the gas

If the lawn mower stops when the throttle is pressed, the reasons may be as follows:.

• The most common option is carburetor adjustment failure, which occurs when the drive is under heavy load, after prolonged inactivity of the mechanism, or when it is used in difficult conditions.
• Clogging of the fuel valve, which is eliminated by loosening it, as a result of which gasoline begins to flow normally through the system.
• Looseness and dangling of the cable in the carburetor. The fuel hose may also be stretched to the point of rupture due to significant stress.
• Clogged breather (check valve), as a result of which fuel does not enter the tank.

If the problem is related to the carburetor unit, then it can be recognized by the appearance of vibrations of the lawn mower.

The chainsaw stalls at high speeds. simple carburetor repair

The carburetor of the instrument is exactly the mechanism that most owners are afraid to disassemble on their own. The reason is that this mechanism consists of many small parts, the location of which must be remembered when carrying out dismantling work. However, not everything is as scary and difficult as it might seem. To understand how the carburetor has to do with the problem of stopping the engine when the engine speed increases, you need to find out its principle of operation, described on the website.

The chainsaw stalls when you press the gas due to the carburetor, if:

• Diaphragm damaged
• Clogged filter element (mesh in the carburetor). This malfunction can be encountered by owners of tools who do not have a fuel filter or it is simply disconnected from the fuel hose.
• Needle sticking, which may be due to outdated fuel mixture
• Clogged nozzles or clogged carburetor
• Bending of the connecting part connecting the membrane with the needle to supply fuel to the fuel chamber of the carburetor. This part is also called a foot, since under the influence of the membrane on it, the needle moves and the channel opens. During operation, this foot can bend (work out) or break (the engine will not start if it breaks). If the foot is bent, then it can be unbent, but this does not guarantee that the problem will soon recur, therefore it is recommended to replace the part

It is recommended to clean and wash the chainsaw carburetor, as well as replace defective parts and elements. After that, you can put it back, not forgetting to also replace (if worn out) the gasket between the carburetor and the adapter.

When the air damper is opened

It happens that the unit stalls when the air damper is opened, normally idling. This is due to air leaks in the system, caused by cracks in the fuel hose or problems with the oil seals. The carburetor metering system may also malfunction, and the lawn mower will stop after opening the damper.

Fuel hose in carburetor

All the possible reasons that the lawn mower stalls, and how to fix them, are contained in the following video.

There are many reasons for stopping lawn mowers, but the most common malfunctions associated with its carburetor. They can occur in any case. The most problematic option is when a serious breakdown occurs, and you need to purchase new parts or change the lawn mower.

In order for the trimmer to work normally for a long time, you must strictly follow the instructions for use. It is necessary to fill the unit with a suitable fuel mixture, the unit should operate at moderate load.

Stalls at high speeds

When the chainsaw starts to stall at high speeds, the following parts must be checked:

• air filter;
• fuel pump;
• fuel filter.

The air filter must be cleaned, for which it is enough to wash and dry it (paper filter. only change). You can check for a clogged fuel filter by disconnecting the fuel hose from the carburetor. If the trickle of gas from the hose is flowing well, then checking or replacing the fuel filter need not be performed. If the trickle is weak or there are no signs of fuel supply at all, then the filter should be replaced and the breather should be cleaned with a regular needle.

Checking the fuel pump is checked for characteristic signs of fuel seeping through it. If there are no signs of leakage, then everything is in order, then it remains to check the carburetor. Depending on the saw power, the maximum speed is set, which can be checked using an electronic tachometer.

As you can see from the description, there are a lot of reasons why the chainsaw starts and stalls. Most often, this occurs due to an incorrect carburetor setting, although on branded chainsaws, such as Stihl, Husquarna, adjusting the carburetor is a rare event if you fill in a high-quality fuel mixture. If malfunctions and malfunctions occur in the operation of the tool, it is recommended to diagnose and repair it, and continue using it only after eliminating the malfunction. It is not uncommon for small signs of malfunctioning to become serious problems for tool owners.

If stalled at high speeds

If the carburetor stalls at high speeds, this means that at idle and low speeds, the incoming fuel is enough for it, but not enough to work at high speeds. Then it is necessary to check the health of the following trimmer assemblies.

• Fuel hose. may have been damaged by cracking. In this case, you need to replace the part. Or maybe you just need to tighten the clamps.
• The filter mesh between the carburetor and the gasoline supply hose. it could be clogged. In this situation, it is necessary to clean the part.
• The valve located on the gas tank cap. it could get stuck or clogged with debris. Cleaning is also needed.
• Carburetor. it may be misaligned as a result of constant vibration. This is usually the case for cheap Chinese parts. To fix the problem, you need to configure according to the instructions. In some cases, it is enough just to loosen the tightening of the carburetor body. If the adjustment fails, you need to install a new element.
• Additionally, you should check the air filter. It may need to be rinsed and cleaned or replaced with a new one, as it could get clogged with dirt and grass particles when the equipment is tilted, when the user mowed in hard-to-reach places.

The lawn mower stalls when you press the gas, how to fix a breakdown

Likewise, when the throttle is pressed, the tool stalls because the actuator is clogged. The following option is also possible: the fuel does not come in full volume, so you need to check or replace the fuel filter. Other possible reasons for stalled lawn mowers when giving gas include:

• Crankshaft oil seals suck in air;
• A spacer that is located between the carburetor and the cylinder in a “problem” situation;

To all of these reasons why the mechanism stalls when gas is added, we will add some helpful tips on how to handle your lawn mower. First of all, before starting work with any technique, you need to read the instructions. In this case, the consistency of gasoline and oil plays an important role, it is competently prepared by you, and also not to overheat the unit, and not to leave gasoline for the winter when you simply will not use the car.

The well-coordinated work of all its components plays an important role in the full-fledged work of any tool. And if in one it is a line for lawn mowers, then in the other it is a piston or a carburetor. Lawnmower owners who want to use their tool at full capacity need to understand that under a load for which the machine’s capabilities are not designed, the entire mechanism or its individual parts can simply break. Therefore, only competent and moderate operation presupposes long-term efficient operation of any gasoline-powered tool.

If stalled after launch

If the equipment starts and stalls immediately after starting, this indicates an incorrect setting or misalignment of the device. As a result, fuel does not flow to the engine evenly, resulting in significant vibration and trim disengagement. To fix the breakdown, it is necessary to reconfigure the device according to the user’s manual.

Another probable problem is a clogged gasoline supply valve. It needs to be cleaned.

On a note! If the trimmer starts but stalls immediately, it may also mean that fuel is having difficulty moving to the carburetor. The weakening of the valve will help to eliminate the problem. this will ensure uniform and free circulation of fuel in the device.

Another possible cause is a damaged fuel intake hose. Air can enter the system through cracks and holes. To solve the problem, you need to increase the engine speed in order to get rid of air bubbles that have penetrated into the device.

If stalled under load

Sometimes the trimmer stalls under load because it cannot gain momentum. This means that the cable, which is taut in the carburetor, is loose and slack. If you have experience in repairing this unit, the cable should be tightened.

Another cause of the malfunction is that the fuel intake hose is too tight. Under load, it stretches even more, as a result of which cracks are formed, as a result, the part deteriorates. To eliminate the breakdown, you will need to replace this element.

If stalled when heated

the lawn mower often stalls when heated. It looks like this. the tool starts up, works “jerky” (not smoothly) and quickly stalls. This situation occurs due to fuel boiling in the carburetor or an incorrectly selected damper, which should not be disk, but rotary. In the latter case, if an error is found, the part must be replaced.

Damaged ignition circuit wiring or a defective coil can cause trimmer to heat up. Broken knot will need to be replaced with a new one.

If it stalled when opening the damper

If the equipment works properly at idle, but stalls when the air damper is opened, this indicates the penetration of air into the system through cracks in the fuel supply hose or damaged oil seals. In order to fix the breakage and adjust the operation of the tool without sucking air from the atmosphere, it is necessary to replace the damaged parts.

How To Easily Fix A Weedeater That Bogs Down

Another possible cause of a breakdown is a malfunction of the carburetor dosage system. To fix this problem, it is better to contact the professionals.

Trimmer stalls at idle. reasons and solutions

Common situations where a trimmer or lawn mower stalls is idling. Let’s go straight to the reasons:

• heating of the gearbox and a drop in revolutions on the drum as a result of the gasoline solution not being prepared quite correctly. The required proportion is 1: 4;
• contamination of the carburetor;
• the throttle valve is clogged;
• when the damper is opened (if such an experiment was carried out), the air flow makes the mixture “lean”;
• adjusting the carburetor;
• clogged air filter;

Insufficient amount of fuel, which is needed for the operation of the gasoline-powered tool, will entail a situation when at high speeds, with an increase, the trimmer works, and at idle it stalls. In a situation with a carburetor, the device will stall on cold start and “hot”. For any lawn mower user. a professional and an amateur, it is important to understand that any malfunction of the tool may depend on fine flaking of the part, detachment of the fastener or clogging, as well as on the global breakdown of an important part of the mechanism.

Despite all sorts of malfunctions, your device still needs such an indispensable component as lawn mower knives, without which the operation of the scythe is simply impossible.!

Weedeater starts but dies. Easy quick fix.

The petrol trimmer is a useful tool for clearing unwanted grass from house areas and large lawns. The design of this technique is quite complex, therefore, if the device breaks down, there may be several reasons. The most likely factors causing the breakdown are usually described in the user manual. Knowing why the trimmer stalls, you can try to fix the defect yourself. The most common malfunctions that provoke a stop of lawn mowers, and the possibility of repairing them with your own hands. in the material below.

Power failure

The car brakes when the accelerator pedal is pressed due to improper operation of the power system. This problem can arise for a variety of reasons. It often arises from the use of low-quality fuel. The fact is that low-quality gasoline contains mechanical impurities that lead to clogging of the power system (filter, nozzles).

If the blockage is not strong, then dips appear occasionally when the gas pedal is pressed. In case of severe clogging, accordingly, no fuel enters the combustion chamber at all. This leads to the fact that the engine becomes impossible to start.

If such a problem occurs, then all fuel supply elements should be checked. First of all, it is necessary to assess the condition of the pump. It must be removed and checked.

With a working pump in one of the directions along the mowing line of fuel movement, gasoline passes unhindered. When such a process is not observed, then we can safely talk about the presence of a blockage. In this case, the pump housing is disassembled and the filter diaphragm is cleaned.

If the pump is in order, you will need to flush the nozzles. Typically, this operation is performed using ultrasound. This is done in the conditions of a service center. In order to prevent the occurrence of this problem in the future, it is necessary to use only high-quality and proven fuel for the car.

Please note that a lack of ventilation in the fuel tank can also cause the engine to stall. Ventilation is impaired due to clogged drain tube. If fuel is suddenly supplied from the tank to the engine, then a vacuum develops. It is easy to check for this problem. It is necessary to start the engine with an open petrol tank. If the drain pipe is dirty, the engine starts easily when the gas tank is open.

Vacuum leak as a possible cause of engine shutdown

If, when you press the gas pedals, the car refuses to go regardless of the weather conditions, then the problem may be more serious. The fuel system of the car is probably out of order. Vacuum leaks are common. With such a problem, the engine starts to shut off occasionally, then the problem becomes more frequent.

Vacuum leaks have a negative effect on the state of the air-gas mixture. Therefore, the engine stalls when a person presses the pedal.

Vacuum leaks can also be identified by looking at the “Check Engine” lamp. However, such diagnostics can only be carried out by a highly qualified specialist. It is necessary to take the car to a service center, asking to check the vehicle for leaks.

Can weather affect engine performance??

If the engine stalls when you press the gas pedal, pay attention to the weather. If this situation occurs in the presence of humid air or in rain, it is possible that a lot of moisture has accumulated on the distributor. In case of high humidity or rain, water gets on the ignition distributors. This is because when the vehicle is stationary for a long time, a humid environment forms inside the distributor cap.

Often, the shape of the junction cover allows the vehicle to misfire. As a result of this misfire, electricity stops flowing to the spark plugs. At idle, this problem may not arise. This situation occurs mainly when you press the gas pedal.

The fact is that if you press the pedal, the distributor starts to work much faster. Much more current begins to pass through it. If the environment is humid, the chances of misfire are greater. As a result, the motor does not receive the proper amount of “spark” and stalls.

It is not difficult to confirm the existence of just such a reason for the failure of the car. To do this, you need to pay attention to whether this problem occurs when the engine is in a warm state, and the weather is dry at the same time.

If the weather is still damp, and you need to check the operation of the car for performance, then you can simply put the car in the garage for a certain period of time.

Ignition problem

If the vehicle has ignition problems, the spark is very weak. If you press the gas sharply, the filling of the candles is noted. Candles are flooded and the spark fading is noted.

It is not difficult to test this hypothesis. When you unscrew the candle, it will become noticeable that it is wet. If there is a suspicion that there is a problem with the ignition, it is necessary to check the entire system.

Long service of candles can lead to such a problem as breaking through to the body.

The high voltage wires can be checked using the spare kit. If it is absent, you can start the engine at night by looking under the hood. If the wires are damaged, then current discharges can be noted.

If such a breakdown as jamming the car when you press the gas is a frequent occurrence, then it is better to seek help from professionals.

Worn gaskets

The design feature of the engine assumes the presence of gaskets. They make the engine more sealed. If the gaskets in the area of ​​the collector or cylinder block are worn out or have lost their tightness, then when the gas pedal is pressed, the engine may stall.

If the gasket is burnt out, then coolant enters the engine in the area of ​​the cylinder block. In this situation, the engine continues to run, but the number of revolutions decreases sharply. You may notice the presence of white smoke from the exhaust pipe.

The driver, faced with the problem of engine shutdown, finds himself in an extremely unpleasant situation. In order to eliminate this complexity, you need to know the cause of its occurrence.

Electronics problems

Unstable operation of the motor can be observed due to difficulties with the electronic system of the car. A large number of operations in the machine are carried out under the control of the ECU. If the sensors malfunction, then they send erroneous commands to the engine. In most cases, the throttle sensor suffers.

The error lies in improper idle operation. Normally, when the gas is pressed, the volume of the supplied fuel should increase, but in reality, on the contrary, it only becomes less or completely stops. If you correctly adjust the sensor in the service center, then you can solve this problem.

The coolant temperature sensor can also cause the car to brake when the accelerator pedal is depressed. If the sensor is broken, then the engine stops working at high speeds. The ECU system is triggered. In the absence of any signals from the sensor, the engine speed may drop to zero.

If the driver wants to turn up the throttle, the engine is turned off. The sensor needs to be checked. In most cases, its repair is impossible, the sensor is replaced with a new device.

The engine stalls when you press the gas pedal. the main reasons

Often there is such a problem when the engine stalls when the driver presses the gas pedal. You can find out the reasons for this situation yourself. They can be different.

Engine stalls regularly. breakdown of the throttle position sensor

Regular shutdown of the car engine may indicate that the problem is a malfunction of the throttle sensor. This sensor measures the force when you press the gas. The data is sent to the ECU (electronic control unit) of the propulsion system. The calculation of the amount of fuel that should be injected into the combustion chamber of the engine is carried out.

This operation is carried out unnoticed by the driver, in a split second.

If the damper sensor delivers erroneous information, the injection of the required amount of fuel may not occur. Such a moment can often be observed when the driver presses the gas pedal. Only a mechanic can perform a quality check of the sensor’s functioning. This requires special knowledge.

As an additional signal, you can pay attention to the “Check Engine” indicator. If it is on, then we can assume that there is a breakdown of the throttle sensor.

When you press the gas, the chainsaw starts to stall. reasons and solutions to the problem

The chainsaw is a highly efficient tool for working with wood. However, the high-speed motor of this tool can be used for a variety of other tasks, which is achieved through special attachments. Sometimes a malfunction such as the chainsaw stalls when you press the gas, which can be triggered by some factors. In order not to have to disassemble the tool completely, we will consider all sorts of reasons for this problem with a detailed description of how to fix them.

The chainsaw stalls at high speeds. simple carburetor repair

The carburetor of the instrument is exactly the mechanism that most owners are afraid to disassemble on their own. The reason is that this mechanism consists of many small parts, the location of which must be remembered when carrying out dismantling work. However, not everything is as scary and difficult as it might seem. To understand how the carburetor has to do with the problem of stopping the engine when the engine speed increases, you need to find out its principle of operation, described on the website.

The chainsaw stalls when you press the gas due to the carburetor, if:

• Diaphragm damaged
• Clogged filter element (mesh in the carburetor). This malfunction can be encountered by owners of tools who do not have a fuel filter or it is simply disconnected from the fuel hose.
• Needle sticking, which may be due to outdated fuel mixture
• Clogged nozzles or clogged carburetor
• Bending of the connecting part connecting the membrane with the needle to supply fuel to the fuel chamber of the carburetor. This part is also called a foot, since under the influence of the membrane on it, the needle moves and the channel opens. During operation, this foot can bend (work out) or break (the engine will not start if it breaks). If the foot is bent, then it can be unbent, but this does not guarantee that the problem will soon recur, therefore it is recommended to replace the part

It is recommended to clean and wash the chainsaw carburetor, as well as replace defective parts and elements. After that, you can put it back, not forgetting to also replace (if worn out) the gasket between the carburetor and the adapter.

Adjusting the carburetor when the engine stalls when accelerating

If the check showed that the fuel supply system, muffler and spark plug are in good working order, then you need to look for a breakdown in other places. Initially, do not rush to disassemble the cylinder-piston group or change the carburetor. It is recommended to start repairs by adjusting the carburetor. For this, all chainsaws have special adjusting screws. They are designed to adjust the idle speed, as well as adjust the fuel supply at low and high speeds. A detailed description of how to adjust the carburetor of a chainsaw is described on the website.

Today we will consider the features of setting the carburetor at maximum speed. You can make sure that the chainsaw is not developing full power using a tachometer. If there is no device, then you can make sure that the engine does not develop maximum speed by ear. We are interested in the screw on the carburetor. Which is for setting high rpm. It is usually denoted by the Latin letter “H”, which is abbreviated from the word “High” (high or large).

To adjust the high speed of the chainsaw, you will need to perform the following manipulations:

• Tighten screw H clockwise until it stops.
• Next, you need to loosen it by 1.25-1.5 turns
• Run the tool and test the speed performance

It is recommended to adjust the tachometer, but if it is not there, then you can check the maximum speed when the tool is working under load.

After a banal carburetor setting, you can fix the problem with the termination of the engine when the speed rises. It should be noted that it is necessary to adjust the carburetor of the chainsaw regularly, depending on the frequency of operation of the tool. It is not difficult to do this on your own, but you can achieve accurate tuning in one case. if you use a tachometer.

Why else can a chainsaw stall when you press the gas

If, after adjusting the carburetor of the chainsaw, the problem remains, then you should resort to checking a number of other factors. There are enough of such factors, and their verification must be carried out sequentially, moving from the easier to the more complex. It is in this order that we will consider all the reasons why the chainsaw does not develop high revs, and at the same time stalls. It should be noted that in this case, the tool starts up and works properly at idle speed.

• Check the chain tension. if the cutting element is tightened too much, this will put a heavy load on the engine. In this case, it will be difficult for a high-speed engine to turn the chain, as a result of which we get its termination of work. The problem can be corrected if the chain tension is correctly adjusted. The chain should rotate easily by hand, but keep in mind that at XX it should not move. If the chain moves at idle speed, then you need to adjust the upper screw XX
• The quality of the fuel mixture and the correctness of its preparation. It is recommended to use AI-92 gasoline for the chainsaw. It is mixed with two-stroke oil in appropriate proportions. Although the mixing ratio is indicated on the label of the container with oil, it is necessary to use the data indicated by the tool manufacturer. The optimal value of the mixture of gasoline and oil is 40/1, that is, 25 ml of oil must be added to 1 liter of gasoline. The proportion means that for 40 liters of gasoline you need to add 1 liter of oil. If you do not adhere to the manufacturer’s recommendations, then in the end this negatively affects the operation of the carburetor and the serviceability of the CPG
• Silencer. very often sawfillers do not pay enough attention to the exhaust system of the tool. If the muffler is clogged, and this necessarily happens over time, this negatively affects the operation of the motor. Silencers on chainsaws are collapsible and non-collapsible. For non-separable devices, the connections are flared, so in case of clogging, you need to either replace the part, or flare for cleaning. A clogged muffler affects the operation of the tool, so do not wait until the chainsaw stops starting
• Air leaks. parts and mechanisms of the chainsaw are connected to the cylinder through gaskets. As a result, such connections are sealed, which is important for the operation of the internal combustion engine. Tightening the bolts and nuts that secure the carburetor and muffler will help to verify such a malfunction. Suction can also occur due to deterioration of the gaskets, which should be replaced on the tool.
• Fuel and air filters are elements responsible for filtering the air and the fuel mixture. If the air filter is clogged, increasing the throttle opening will not allow enough air to flow into the carburetor, causing the spark plug to flood. As a result, the engine will stall when trying to develop maximum speed. If the fuel filter is defective, the required amount of fuel does not enter the carburetor. Its lack leads to the fact that the tool cannot develop momentum, and immediately starts to stall
• The presence of a fuel filter. This element can not only become clogged, but also detach from the fuel hose. As a result, it turns out that dirt will enter the carburetor, which will very quickly disable the mechanism.
• A breather is a hole through which air enters the chainsaw tank, thereby eliminating the creation of a vacuum inside a sealed container. The breather is located on the lid of the gas tank or can be built into the wall of the tank. The principle of its operation is such that as the gasoline in the tank is consumed, the tank is filled with air. If the breather is defective, a vacuum is created in the tank, which prevents fuel from being pumped into the carburetor. The breather allows air to pass in one direction, and eliminates the possibility of fuel leakage from the tank. You can repair the part using a thin needle, which punches a hole
• CPG malfunction. the chainsaw does not pick up speed also if the cylinder-piston group is worn out. To identify this cause, it is not at all necessary to disassemble the engine to look inside. A compressor should be used to check the amount of compression. The normal value should be at least 12 atmospheres, and if the value is lower, then the CPG must be replaced
• Ignition System. If the engine starts, it is unlikely that the problem is an electrical malfunction. However, it will not be superfluous to unscrew the spark plug and visually inspect it. The presence of black carbon indicates the need to check the ignition. The first step is to check the gap between the ignition module and the flywheel, the value of which should be 0.25 mm. The integrity of the armored wire is also checked, and if it is damaged, then it must be replaced along with the module. Spark plugs have an appropriate resource, so they need to be changed, pre-setting a gap of 0.5-0.7 mm (indicated in the technical description for each tool model)

If checking all the reasons does not allow a positive result to be achieved, then the carburetor of the chainsaw should be removed and cleaned.

Where to look for the reason or where to start checking

All chainsaws have the same design and work according to the same principle. The chainsaw device can be found in this material. It does not matter which brand of tool. Stihl, Husqvarna, ECHO, Champion, Partner, Shturm and others. A malfunction that manifests itself in the form when the chainsaw stalls when you press the gas can occur equally both on expensive and high-quality tools and on budget Chinese devices. If a problem occurs, then it needs to be solved.

A chainsaw is a system of mechanisms consisting of parts. Any part in the mechanism can fail, which will lead to partial or complete failure of the tool. If the engine of the tool starts, this does not mean that the chainsaw is completely operational. When the engine stops working when the engine speed rises, there are corresponding reasons for this. With this malfunction, attention should be paid initially to a number of the following tool mechanisms:

• Gas tank. make sure there is fuel. If there is sufficient fuel, you should also check the serviceability of the fuel filter, the presence of the connection of the supply hose with the carburetor, and also make sure that the breather is working

These are the main parts and mechanisms that should be checked first of all if a malfunction occurs when the chainsaw stalls when the accelerator is pressed. There are other reasons why a chainsaw engine stalls when the gas trigger is pulled. What else can contribute to the occurrence of this malfunction, as well as the features of eliminating breakdowns, we will find out further.

Why the chainsaw stalls when the accelerator is pressed. summing up

When making an upgrade for the reasons why the saw stalls after you press the gas, you need to take stock of all sorts of reasons and their elimination. The reasons can be conditionally divided into two parts. simple and complex. You need to start troubleshooting with simple reasons, and end with more complex ones.

You definitely need to start the check from the tank, not from the carburetor, but from the gas tank. And make sure you are using a properly prepared mixture. Next, you need to check the serviceability of the muffler and the presence of carbon deposits on the spark plug. After that, you will already have an idea of ​​in which part of the tool you need to look for a breakdown. Perhaps a breakdown is. That you just need to wind up the maximum speed, for which the carburetor is tuned. If this does not solve the problem, then you should check the air filter and clean it.

Pay special attention to the carburetor, after cleaning and possibly repairing which the chainsaw should work like new. If even after this the problem remains, then do not be too lazy to check the amount of compression. Perhaps the engine has a strong performance, and needs to be replaced.

This completes the upgrade to restore the tool’s performance, and it is worth noting one more point, such as the use of fuel that has been stored for a long time. Many people dilute gasoline with oil, and store the mixture for months, and sometimes for six months. This cannot be done in any way, since the mixture has the properties of aging, and therefore, after its preparation, it must be used within 1-2 weeks. If you do not follow this recommendation, then you will often need to change not only the fuel filters, but also clean the carburetor, but the worst thing is that this contributes to accelerated wear of the CPG.
