Does not pump gasoline champion gasoline. Violation of the sequence of actions when starting to cold

Why does not apply gasoline into a chainsaw

If during the launch and operation of the tool its owner hears sounds resembling shots, then this indicates a malfunction of the node in which the fuel is mixed. The reason for this, most likely, are such malfunctions of the carburetor of the chainsaw:

  • The tattered ignition. in this case, the fuel does not burn out, which leads to specific sharp shots;
  • The supply of a low concentration of gasoline to the carburetor. to fix the problem, you will need to configure the nozzles.

If the shooting sound comes from the side of the muffler, then the problem is to oversaturate the fuel mixture with gasoline. If there is too little air in the fuel, then it will burn not only in the chamber, but also in the muffler. Evidence of this will serve as a large amount of soil on the inner walls of the muffler.

Each modern chainsaw, regardless of its purpose and design features, is equipped with a fuel system. It is based on a carburetor, the main function of which is to mix the fuel mixture with previously purified air. Any malfunction of the carburetor leads to power loss and other problems with the garden benchmain. You can solve them yourself. for this you need to study the design of the fuel unit, the features of its adjustment and methods of independent repair.

What to do if the chainsaw does not start further?

If the initial inspection did not give anything or the defects in the search process were eliminated, and the chainsaws are not started, then you need to look for more serious reasons. It is best to identify and eliminate such breakdowns in the service center. However, in the presence of experience, you can find and eliminate them independently. What to diagnose and check?

In the first case, checking the compression in the cylinder will find out the condition of the cylinder.piston group (CPG) of the chainsaws that does not want to start on the cold. To do this, you need a compressometer. The device is screwed into the spark plug and the engine is idle. The measurement of indications allows you to judge the state of the CPG. In the absence of a compressometer, it is possible to determine the compression in the cylinder as follows:

By putting a finger to the candle hole and twitching the starter, you can check the compression in the cylinder

If you feel that the finger is strongly drawn into the candle channel, then everything is in order with compression. Lack of discharge in the cell, indicates the presence of a malfunction. The cylinder.piston group needs a more detailed examination, which will give an idea of ​​the state of the piston and cylinder, piston rings and bearings.

You can’t start a chainsaw on a cold one due to the lack of compression in the engine crankcase. The main reason for this is the damage to the gasket placed between the cylinder and the crankcase. It is quite easy to identify the lack of compression:

  • Disconnect the upper tube from the carburetor;
  • Pour gasoline into ordinary cork;
  • We immerse in the fuel removed the tube;
  • We pull the starter several times.

If the fuel from the lid is absorbed when the starter of the chainsaw is launched, then everything is in order with compression. If not, see the gasket.

If the fuel is drawn, then everything is in the strand. the gasket is the whole. Otherwise, you will have to purchase a reptile and replace. How to do this watch the video, why the Chinese chainsaw is not started:

The launch of the tool can be complicated by the incorrect operation of the carburetor or its breakdown. It often happens that in the process of cutting, the fixing screws are weakened and the air sucks into the cylinder. Check the reliability of the carburetor mounting. Inspect it for fuel leaks. The causes of the malfunction may be a mass. It is possible to accurately determine the malfunction, eliminate it and carry out subtle adjustment of the carburetor only in the service center.

Having passed the cheeky defect of the chainsaw engine, you can find a malfunction, eliminate it yourself and successfully start your working tool. Do not take up those types of work that you are not sure. Trust the search and elimination of a malfunction to specialists from the service center.

The device of the chainsaw

Apart from the listed nodes, the chainsaws have a system of cleaning the air entering the carburetor, the tire with the pollen chain, the starter, the mechanism of tension of the chain, ignition, the silencer, etc.D.


Below is the scheme of another carburetor of the chainsaw.

Carburetors have a throttle valve, which allows the consistency to be watery or richer, depending on the criterion of operation. For a narrow option, there are several screws with which you can adjust the low and highest frequency of rotation of the motor, also the speed of idle. The floor of the carburetor is installed an air filter that cleans the air entering it.

Ignition system

The electric ignition of the chainsaw includes the flywheel (1) with magnets, the ignition module (2) with an electrical circuit, the spark plug (3) and the high.voltage wire (4). A spinning flywheel with magnets causes an electric motor in the module, which is converted by an electronic signals, supplied to the candle. As a result, the spark jumps between the contacts of the latter, lighting the air-fuel mixture.


The chainsaw engine has the highest speed of about thirteen 500 rpm. This makes strict requirements for the oil attached to the fuel consistency.

Why is the chainsaws badly starting

Consider each reason in more detail.

Fuel and air filter

Pollution of the main filter elements of the chainsaw, adversely affect its work.

For example, a dirty air filter will provide air supply to the carburetor in full, which will affect the quality of the fuel mixture and normal engine start. Fuel filter pollution will make it difficult, or even reduce the supply of gasoline to the carburetor and make the engine to work impossible.

Reduced compression

One of the frequent cases of the difficulty starting of the chainsaw is the wear of the CPG (cylinder.piston group).

As you know, for the normal launch of the chainsaw in its engine, compression should be present. It is necessary for the normal compression of the fuel mixture in the engine cylinder, it also affects the operation of the gasoline pump.

The reasons for the lack of compression, or its decrease, can be natural, The engine wear out during operation. Problems can also be caused by serious breakdown, for example, Zadir CPG, or breakdown of a piston ring.

A sign of reduced compression is the weak resistance of the starter during the start. With reduced compression, a decrease in the power of the chainsaw is observed, which negatively affects its performance. The problem of replacing piston rings, or completely CPH, is eliminated.

Carburetor adjustment

Not correct adjustment of the carburetor will cause the chainsaw will not develop full power. It will be bad to start, or not start at all. The setting of the carburetor directly affects the quality of the fuel.air mixture, which is necessary for normal starting and further engine operation.

Excess gasoline in the mixture, it is customary to call overflow. Characteristic signs of overflow, it is a wet spark plug, after several unsuccessful attempts to start a chainsaw.

Spark plug

Spark plug is one of the main elements of the ignition system. On its electrodes, a spark is formed, and when this element fails, it will be difficult to start, or it is not at all possible.

The candle can completely refuse, or work with interruptions or give out a weak spark. Checking the candle is quite simple, for this you will need to unscrew it from the engine, attach to the cap of the high.voltage wire and, putting it on the cylinder, pull the starter. If the candle is in order, the spark will be powerful with a bluish tint. Weak spark with a reddish tint, a sign of a problem. A defective candle needs to be replaced.

Ignition coil

The reason that a new chainsaw is not started, or it starts poorly, may be a ignition coil. Modern chainsaws are equipped with electronic ignition coils. This part is not subject to repair, and, as a rule, in the presence of a defect, it completely changes.

does, pump, gasoline, sequence, starting

Gap between the ignition coil and flywheel

An unbelievable gap between the flywheel and the contacts of the ignition coil affects the quality of sparking, which in turn is responsible for the normal start and stable engine operation. adjustment of the carburetor of the chainsaw

To independently configure the standard carburetor, the owner of the chainsaw will need a cross or flat screwdriver. as well as manual tachometer.

To adjust the gas.rosopila carburetor. The base device of its carburetor provides for spring.loaded adjusting screws.

Depending on the brand manufacturer of the chain saw, the marking of its adjusting screws may vary. However, to initially correctly configure the carburetor on the chainsaw. You can always act according to the same algorithm:

  • Initially, the operator must find in the instructions for the operation of the saw the exact angles of the gradual rotation of the adjusting spring.loaded screws. Immediately after that, on the used saws with a dried motor, they must be turned according to the instructions in the manual. If you do not do this, the operator risks breaking the engine engine;
  • Further, the chainsaw used on the farm will need to be motionless on a flat stable surface. In this case, the tire and the factory chain should be initially directed away from the operator;
  • Then you need to have a sawtte saw and give it at least 10 minutes to warm up;
  • After that, you need to find the correct position of the screw l. To do this, the operator must slowly turn it along the way and counterclockwise until the engine becomes quietly and without failures;
  • If, as a result of this, the chain began to rotate, then it is necessary to find the position of the screw t, in which the chain will stop in place:
  • Further to the ICE cylinder, you need to connect a tachometer. Then you need to start turning the screw h. As soon as the indicators on the tachometer coincide with the instructions in the instructions of the saw, the screw can be released.

To check the operation of the carburetor and the chainsaw engine, you need to start the engine again and slowly press the gas lever. If the internal combustion engine is smoothly gaining momentum, then the adjustment was performed correctly. If this does not happen, then you will need to turn the screw L to 1/8 turnover against the course of the watch of the clock and again conduct a motor check.

Why does not apply gasoline in a chainsaw?

According to the reviews of the owners of Chinese chainsaws, the technique is often broken and the breakdown is accompanied by the lack of fuel supply to the carburetor. If you have applied the above tips, it is necessary to diagnose the following elements:

The needle of the carburetor. On cheap chainsaws often sticks a needle in a carburetor, which does not allow fuel to act. Sometimes it’s enough just to move the needle and install it correctly.

Basils. Chinese and even branded chainsaws can have low.quality oil seals with poor tightness. Fuel ceases to flow when it begins to squeeze the fuel mixture through the seals. A leak of gasoline is quite possible through the seals.

Sapun check

It is the Sapun who plays a serious role in the establishment of a chainsaw, you can find such a part near the gas tank cover, or rather in the area of ​​the air hole. The sapun plays a simple, but important role. does not allow fuel to flow out and sets the correct air pressure. It is thanks to this air that the fuel enters the carburetor, and the malfunction of this element is a common reason when the fuel does not enter the chainsaw. The impaired the work of the soundtress will serve the formation of negative pressure, from which gasoline will not be able to enter the carburetor when trying to start a tool.

Checking the operability of the cabin is quite simple, disconnect the gasoline of the carburetor pipe and check how the fuel flows. If gasoline flows with a small stream, everything is in order, if it does not flow at all, the sapun is rather clogged with dirt. With proper execution, you can clean the part, sometimes it is easier to replace with a new. The cleaning procedure is performed either manually or by the supply of a strong jet of compressed air.

There is a way to check the supply of oil without removing the tires. To do this, direct the end of the tire to the side, for example, freshly cut stones on the cut side and maximize the speed, while trying to hold the end of the tire at a distance of not more than 10 cm from the cutlet. If fat spots begin to appear on its surface, then oil is supplied.

First repairs warnings

consists of many parts. We highlight the main ones, such as:

10 People You’d Never Want to Mess With

Since this is only a small part of a not very detailed description, it should be borne in mind that the chainsaws are actually similar in their own structure, which greatly simplifies their diagnosis and repair. Repair can be very complicated by the time if you turn to the master and continue to use broken equipment further. And it’s quite right to carry out the repair of the chainsaw, the most perfectly to turn to the master, because the future “life” of your “indispensable partner” depends on the repair.

So, during the repair, the master must check all the details of the chainsaw, why it is disassembled by parts. In most cases, breakdowns arise from incorrect and inaccurate operation of the device, therefore, a fuel filter or a saepa is often clogged with sawdust. For diagnosis, Zasor disconnects the hose and inspects how fuel flows.

Read how to dilute oil for a lawn mower

Fuel can also come in the missing amount. This is due to the fact that the air filter is clogged, so it should be changed once every three months.

One of the principal parts of the chainsaw is a spark plug, which is also certainly necessary to check. The prerequisites of the malfunction are likely to be worthy of attention:

If the candle is dry, the fuel does not enter the cylinder, and this, in turn, means that everything is in order with the ignition and the repairmen look for a different case. If the candle, on the contrary, is in oil, then means that there is an excess of fuel. In this case, you need to turn out the candle and wipe it perfectly, then put back again. Dark Nar on the candle means that during its use, the owner of the chainsaw in incorrect proportions connected gasoline and oil. Will certainly inspect the presence of a spark.

As we see, the repair is still not so simple and we still have almost everything ahead. The process of restoring the performance of the chainsaw contains some processes of cleaning parts of this device, such as muffler. We will analyze this operation in stages. To begin with, as in any repair, we need to find this part of our device, remove it and disassemble. If it has a lot of soot on it, then we need to clean it, and for this they will come in handy:

These items can be found in any house. We completely clean our muffler from the carbon, after that it is fundamentally perfect to dry it, so that the repair does not go in vain and, of course, put it back in place.

Dry cleaning of the silencer is very unsafe for health, the haul contains a lot of carcinogen, which can be inhale in case!

The advantages of the model

Why the chain flies from the tire? There may be several reasons and they are all different:

  • Wear of the leading or led star. Due to the fact that the asterisk has worn out, the clutch with a chain is reduced, which is why the chain from the chainsaw flies flies. A stars are required.
  • The chain stretched. Why the chain is stretched on the chainsaw-due to insufficient lubrication. The metal is heated and stretched, albeit a share of a millimeter, but if you take into account the number of links, then even 3-4 mm is enough for the chain to fly off the tire. It is necessary to change the chain.

Possible malfunctions of the chainsaw Husqvarna 142

As well as any other devices, the operation of which is associated with saturated loads with non.complex criteria, the Husqvarna 100 40 chainsaw is two 40 is two, immediately the prerequisites for the problems are naturally conditionally divided into two groups:

  • Motor breakdown as it is also called the piston group. Tasks with fuel, exhaust or ignition system.
  • Problems that arose in mechanical nodes. the bus, the clutch system, the brake as it is also called the lubricant.

Repair of the GOODLUCK chainsaw carburetor. The principle of operation of the carburetor

Regardless of the manufacturer’s company, the principle and procedure for the operation of the carburetor of internal combustion engines is similar. Adjustment of the carburetor to adjust the carburetor of the chainsaw and

Air under the atmospheric pressure, passing the air cleaner, is supplied to the narrowing zone, where its consumption is regulated by the overlapping section, with a flat damper. After narrowing in the pipe, discharge appears. As a result, the vacuum sucks the fuel from the fuel supply tube, the output from which is regulated by a fuel needle connected to a float chamber with a jackler. The device of the benzopila carburetor, in principle, does not differ from other mixers of fueling internal combustion engines.

The principle of mixing is to regulate the air damper, the level of the float, depending on the degree of discharge. We open the air. more fuel comes, the engine increases the moment. The correct ratio of the combustible consistency is depending on the clear adjustment of the carburetor of the chainsaw. If there is a lot of air in combustible, the power falls, the mixture is called the depleted. With a shortage of air, there is a large fuel consumption, incomplete combustion, a dozen on the cylinder and the release of a unbroken fuel. It says that the mixture is super.saturated.

The Urals by annotation asks for a using enriched fuel consistency. Therefore, the carburetor from the plant comes with the setting for the period of the When switching to the operating mode, the knot is tuned in the ground.

Signs of good operation of the gasopyle carburetor:

How to rinse a gasopyle carburetor?

Think about cleaning the fuel unit of a benzo tool in such cases:

  • if the engine is difficult to launch;
  • with unstable operation of the internal combustion engine at short.term idle;
  • in case of failures by smooth pressing on a regular gas trigger;
  • with a significant increase in the costs of refueling.

Most often, for washing the carburetor of the chainsaw, liquids are used that are in almost every garage:

Modern gardeners using powerful professional saws use more effective and gentle means:

  • Mannol Vergaser Reiniger. Cleaner entering the sale of aerosol. He quickly and easily breaks down even the oldest formations of resins, soot, oily plaque and other types of pollution;
  • HI-GEAR-this cleaner stands out by high dissolution properties. He can bring out old dried spots, oily crust and the first signs of rust without harm to the parts of the fuel system;
  • Jet 100 Ultra. a spray designed to quickly clean the gasopyle carburetor. Shows the high rate of dissolution of the oldest oily spots.

Carburetor cleaning on the chainsaw is performed in the following sequence:

  • First, you need to clean the outer part of the saw engine, as well as dismantle and thoroughly rinse the case of the factory air filter;
  • Next, you can proceed to disassembly of the benzo tool. To do this, remove the filter housing, as well as unscrew the mounts holding the carburetor along with the engine;
  • Then you need to carefully disconnect the traction and gas cable from the carburetor. The springs available in the design must be removed so as not to stretch them;
  • After that, you need to carefully pull the hoses from the factory fittings for the supply of fuel;
  • To clean the carburetor on the chainsaw, you need to remove it from the branded fasteners. At the same time, it is important to maintain the integrity of the gasket installed between the ICE cylinder and the fuel node;
  • At the next stage, you will need to clean the external walls of the carburetor. To do this, they can be treated with a liquid cleaner or gasoline. In this case, you need to try so that dust and garbage do not get inside the node or cylinder of the motor;
  • Next, you need to unscrew the screws of the carburetor diaphragm, remove its lid and rinse the internal cavity with an aerosol cleaner;
  • After that, you need to dismantle the fuel filter of preliminary thin cleaning, as well as disassemble the part of the node to which the fuel is summed up. All the internal details of the carburetor must be thoroughly washed with an aerosol cleaner. If the first cleaning did not bring the result, then the flushing should be repeated.

After the final drying of all the internal details of the standard carburetor, you need to assemble the fuel unit in the reverse sequence, and install it in place in the design of the economic chainsaw.

How to adjust the carburetor of the chainsaw Husqvarna 142

Setting the carburetor of the chainsaw Husqvarna one hundred forty.two should be carried out with a heated engine. Pay attention to the condition of the air filter, which, if necessary, will need to clean and make sure that it is not clogged. Husqvarna chainsaw carburetor adjustment is performed by forty.two with your own hands using three screws:

Turning clockwise the control screws of low and high revolutions, translate them to the limit, and after the peak is reached, scroll them in the opposite direction, one and a half turnover. Babble starts and stalls, the chainsaw of Husqvarna 142 Piston videos. When working at idle, a chain for the chainsaw of Husqvarna one hundred and two should be motionless. Check at maximum speeds.

Avoid most malfunctions and expensive repairs, you can observe the instructions and recommendations of the manufacturer, as well as using original spare parts for the Husqvarna 142 chainsaw.

Recommendations of Profi for the control of the working mixture

If the verification of the proper result was not given, we proceed to checking the ignition. A wet candle of wet indicates an excess of fuel and a lack of air, the mixture, which during launch flows a candle, cannot set fire to a powerful spark in such a proportion.

For the output of the quality and amount of the airborne mixture to the optimal parameter, a wide range of operational adjustments is used. The cause of fuel overflow in old chainsaws may be the leature of the fuel consumable crane and the float valve of the carburetor.

In standard situations, after a short purge of the cylinder, with a candle removed or turned on, the normal start of the launch is completely restored.

The consequences of operation on a rich and poor mixture

Confirmation of normal, in a proportion of 16: 1, the quality of the air fuel mixture is the brown color of the insulator and the absence of traces of soot.

How to adjust the carburetor on a chainsaw correctly?

To configure the node, install the tool on a solid even surface. It is best to regulate the gasopyle carburetor in a place protected from dust and moisture.

The process of setting up the node should look as follows:

  • First you need to unscrew the fasteners and remove the protective file of the saw. This will allow you to inspect the carburetor and, if necessary, clean it;
  • Next, you need to extract the standard tool air filter. If the saw is equipped with an additional foam insert, then it also needs to be removed;
  • After that, you need a screwdriver, which needs to tighten the bolts with the labeling h and l clockwise until it stops. You need to do this very carefully so as not to break the bolts;
  • Then both screws should be unscrewed by 1.5 turns in the opposite direction;
  • Next, you need to start the chainsaw motor and let it work for about 7 minutes;
  • As soon as the motor cylinder heats up, you will need to start turning the Bolt B to the moment until the ICE becomes at maximum speeds. Immediately after this, the bolt must be turned into 1/4 turnover in the opposite direction;
  • Then you need to configure the operation of the motor at high speeds. To do this, you need to connect an electronic tachometer to the engine, and start turning the bolt H until the indicators on the device’s board coincide with the instructions for the recommended maximum speeds in the instructions for the saw;
  • At the end, it remains to set up the work of the internal combustion engine at idle. To do this, you will need to slowly twist the t bolt against the watch arrow until the engine becomes stable and without failures. If the motor began to stall, then the bolt t should turn in the direction of the watch arrow.

To configure the carburetor on the chainsaw, you should work as accurately as possible with adjusting bolts. Excessive twisting of the screws will lead to an increased load on the engine and other important nodes of the garden tool.

10 Most Dangerous Bugs In The World

The chainsaw is stalled and not start

If the tool is stalled and not starting to start, it is worth checking the presence of fuel in the tank. Oddly enough, it sounds, but many people forget about this and, if such a situation arises, they immediately try to repair the tool, which can lead to serious breakdowns.

In a situation when I drank it stalled, and there is still gasoline in the tank, you need to evaluate how the saw worked until this point. Maybe when working at the last moment there was an extraneous sound, rattle, ringing, power loss, or the tool stopped abruptly. All this will allow to pre.assess the situation.

The engine jammed

Quite often there is a situation when the saw worked and sharply stalled, the cause of which was the jamming of the engine, which in turn occurred as a result of a break in the piston skirt, destruction of the crankshaft bearing, the outbuilding ring of the piston fingers or the break of the piston ring.

The engine jamming is easy to determine if you pull the starter cord. In the case when the starter does not turn, most likely, it jammed, and further repair is possible only in the service center.

The cliff of the fuel wire

During the operation of the chainsaw, vibration occurs, which can cause damage or breakthrough of the fuel line of the chainsaw. In this case, the chainsaw will stall and it will be impossible to start the launch. To diagnose a malfunction, you need to conduct an inspection and determine the presence of fuel fuel.


Overheating of the engine during operation may cause the saw to be stalled and will not start. Overheating is quite dangerous, as it can cause melting the piston in the cylinder and jamming of the engine. In the first cases of overheating, it is worth diagnosing the tool for the availability of extraneous air leaks to the engine, and adjusting the carburetor.

Air leakage, as well as the correct adjustment of the carburetor affects the maximum number of engine speeds and its lubricant, which in turn causes overheating and shaking the tool.
