How to remove a carburetor from a Stihl 180 chainsaw

The Stihl MS 180 chainsaws are designed in such a way as to make their operation as allegedly asleep as inexperienced users as much as possible.

To do this, some settings available on more powerful StiHL models were abolished in the carburetor of the saw.

But there is still an opportunity to set up, and repair, as well as adjusting the Carburetor of the Stihl 180 chainsaw with your own hands, is possible.

When you need to adjust the STIHL 180 carburetor

First you should decide why it may generally need to regulate and repair the STIHL MS 180 carburetor. So, this must be done in the following cases:

• if the chainsaw does not hold idle turn;
• Repair may be required if the saw does not start;
• power loss is observed;
• increased fuel consumption;
• chainsaw does not develop maximum speed.
• stalls when recruiting.

This list can be continued for a long time, but we have determined the main reasons. Before starting adjustment, you need to know what main parts a carburetor on the Stihl 180 chainsaw consists of, and who produces it.

Stihl carburetor device

So, the STIHL MS 180 carburetor is developed and produced by the subsidiary of STIHL, called Zama. Original carburetors, on their building have a company logo guaranteeing product quality.

Fuel pump

Directly in the carburetor case, a fuel pump is installed, which works under the influence of an air pulse from the chainsaw crankcase, transmitted through special channels.

The pump has a diaphragm, it is she who is responsible for pumping fuel under the influence of a pulse.

Between the diaphragm and the case, a laying is installed, which is responsible for the tightness of the fuel pump.

Distribution camera

In the distribution chamber, as in the fuel pump, there is also a membrane that opens and regulates the fuel supply by pressing a special rocker, while lifting its needle valve.

The camera cover is the compensator case, which is mounted on the carburetor using four screws, a gasket is installed between the case and the lid, increasing the height of the camera and responsible for sealing.

Nozzle

The nozzle for supplying fuel is mounted in the carburetor case in such a way that it is a connecting link between the distribution chamber and the cavity in which the throttle is installed.

Simultaneously with the fuel, air is supplied to the nozzle and the air mixture is formed.

The nozzle has a check valve that blocks the flow of air in the reverse sequence, that is, from the throttle chamber into the distribution chamber.

The shuttle of the throttle

The throttle is installed in the carburetor case and is responsible for increasing the supply of fuel mixture directly to the engine cylinder.

At the time of pressing the gas, the throttle is opened, thereby increasing the throughput of the channel and fuel from the carburetor cavity, rushes into the cylinder in a larger volume.

Combustion of a larger fuel volume increases the amount of energy formed, which affects the power and speed of processes. The damper is installed on the shaft of the carburetor passing through the entire body.

At the output of the shaft from the housing, a mount for the gas cable is installed, a cone.shaped, adjusting screw responsible for configuring the idle walk is located nearby.

By twisting the screw, you can slightly adjust the position of the shaft and the shutters installed on it, thereby increase or decrease the idle stroke, opening or vice versa covering the damper.

Air damper

The carburetor air damper is installed on the opposite side of the throttle and is responsible for the launch of the cold engine, its control is carried out by the engine control lever. For cold launch, the air damper is completely blocked, for normal operation, open.

STIHL carburetor adjustment

STIHL 180 chainsaw carburetor, indiscriminately, can only be adjusted for the number of revolutions at idle.

Increase or reduce fuel supply in various modes using special screws cannot. The manufacturer limits access to adjustments and does not set these screws.

How to adjust the carburetor to the correct idle speed is described in great detail in the manufacturer’s instructions.

If certain malfunctions occur, and the presence of experience, you can increase or reduce the fuel supply by increasing the gap when the needle valve is opened.

To increase the feed, the rocker of the needle valve in the distribution chamber must bend up, and to reduce, down. Thereby adjust the needle and, accordingly, valve throughput.

Do not adjust your own adjustment, t. to. This must be done very accurately and with an error, it is almost impossible to return the starting position of the rocker.

Why is the STIHL 180 carburetor pouring and several characteristic malfunctions

After we examined the device of the carburetor to determine the reason why the fuel enters the combustion chamber in a larger volume is not difficult. This happens due to wear of the gasket between the compensator cover and the carburetor body. You will ask how this can affect?

The answer is simple, contracting, the gasket releases the diaphragm on top of it on a share of millimeters down. She, in turn, will push the needle valve more strongly on the rocker, it will open more than the laid and the fuel will come in abundance (she will begin to pour).

Another reason is the stretching of the diaphragm itself, this occurs as a result of natural wear. It is impossible to prevent this process, but you can solve the problem by periodically changing all the gaskets, the diaphragm of the carburetor, and the fuel pump. For this there is a repair kit.

When cleaning the chainsaws with compressed air, in no case should you blow into the fuel tube, this can lead to stretching the diaphragm.

Frequent breakdown of the Stihl carburetor and how to avoid it

A common cause of failure of the carburetor on the Stihl chainsaw is the sticking of the valve in the nozzle. The reason for the sticking is a violation of the storage of a chainsaw, more precisely, the instructions of the manufacturer STIHL 180 for proper preparation for storage.

How to remove a carburetor from a Stihl 180 chainsaw

Carburetor Sthil MS180 (Stihl 180). Adjustment. no, I have not heard

On the chainsaw of the Stihl MS 180, carburetors of Chinese.made are being installed currently and in the past couple of years, which have only one adjustment screw. Description of the common malfunctions of the Stihl 180 chainsaw with the carburetor system. Adjustment of the Carburetor of the Stihl 180 chainsaws with your own hands you can configure. Such membrane carburetors are practically not subject to disassembly, since it is all overwhelmed and flooded. Repair of the chainsaw of Stihl 180 with your own hands. The carburetor makes itself felt to remove the lid with. So to speak: “Adjustment. no, did not hear”In this case, it is easier to buy a carburetor of a chainsaw STIHL 180. over, there are carburetors on sale both original (also produced in the PRC, but at the factory belonging to STIHL), and from third.party (also Chinese) manufacturers.

It should be noted that despite Chinese production, the original STIHL 180 carburetors are very reliable and rarely summarize the owners then the original 2500, that is, almost 4 times more expensive.

For the released chainsaws for 5 years or more years, it is possible to purchase reprimatoes.

STIHL MS 180 Carburetor Repair

In this video, we will consider in detail the fuel system of the chainsaw of the Stihl 180 chainsaw

How to configure the carburetor of the chainsaw of Stihl 180?

Only idle adjustment is available to us. Why is it necessary and how to understand when you need to configure idle speeds not the Stihl 180 chainsaw? This is necessary if the chain does not stop at idle, which can lead to injuries, unstable operation of the saw in general.

The procedure for adjusting the STIHL MS 180 carburetor:

In the instructions for MS 180 it is described how to standardly configure idle on a chainsaw:

We turn the blanket of the idle speed against the sentry until it does not go tight, then we turn it off for two clockwork clockwork. How to remove magneto from a chainsaw, video, watch. Voila! Tun

If your saw has too low idle speeds, then we carry out the following actions:

If you have high speeds and the chain does not stop spinning:

• We turn the blanket adjustment screw counterclockwise until the chain stops moving.
• We rotate the screw even on a hollow against the sentry.

If you fail to independently adjust the idle speed, you must contact a specialized service center.

Carburetor device

The Partner 340 chainsaw carburetor housing is made of aluminum alloy. It has technological channels through which a mixture of fuel with oil and diffuser moves. The task of the latter includes mixing air with gasoline, thereby forming a combustible mixture.

The main elements of the carburetor include:

• fuel pump;
• main camera with a membrane;
• throttle and air shutters;
• screws (quality adjustment, quantity, idle);
• needle valve;
• Fuel nozzles.

The device of the lubrication system

Depending on the brand of the chainsaw, the details of the lubricant can differ a little structurally, but their total number and connection scheme remains unchanged.

The main components of the details of the lubrication system are:

• Oil tank located, as a rule, in the engine crankcase.
• Filtering element, installed in the tank.
• Oil wiring, this is a small diameter hose made of oil.resistant rubber.
• The heart of the system is an oil pump.
• Worm gear gears transmitting force from engine to the pump.
• The tire of the chainsaw, it can also be considered an element of the lubricant system, as it has special openings for oil supply, by the way, the chain itself is involved in the transportation of the oil and, accordingly, also has some elements designed specifically to ensure lubrication.

Repair of the carburetor of the Chinese chainsaw

Carburetors worth 500-1000 do not always make sense to repair. A remote control with a set of gaskets and aperture is not much smaller than the cheapest carburetor, 300-350 Frequent breakdown of Chinese carburetors-the failure of the nozzle valve, and such a part is not sold in the remote controls. Therefore, it’s easier to buy a new carburetor.

But there are breakdowns that can be relatively simply fixed on their own:

Loss of tightness between the parts of the carburetor case or between the carburetor and the engine. Sometimes it is enough to tighten the mounting screws. In other cases, you can remove the carburetor, replace the gaskets, or use a suitable sealant with them.

Obvious mechanical problems. deformation of wire thrust from the handle of gas, jamming of the axes on which throttle and air shutters rotate is also easy to eliminate. The thrust is straightened. The sites of the axes are lubricated with a drop of oil and develop free rotation by hand.

Carburetor cleaning

Periodically required to clean the carburetor air filter. They are different types. It is enough to knock out dust and dirt out of some, tapping wood. Others are washed with soapy water. Still others require disassembly. The fourth is almost impossible to clean, it is required to replace with a new.

Features of the air filter of each chainsaw and maintenance rules are described in the operating manual for each specific model.

If there is a filter in a gas tank in a carburetor, nothing can clog anything. If there are still suspicions that tiny holes in a jacket are clogged, the carburetor is disassembled. Details are laid out into clean fabric, remembering what. Holes are blown by a pump or compressor. The case and parts are washed in kerosene or gasoline.

No need to bring the condition of the filters to such a deplorable state. This greatly affects the performance and resource of the chainsaw engine

Gasoline does not enter the carburetor: what to do

The fuel trim from the gas tank is short and simple. Three problems may occur on this site:

• Squeeze the gasoline supply hose. They find a fracture, the hose is straightened or changed if the round shape is not restored.
• The filter was clogged at the bottom of the gas tank, which is installed on some models of chainsaw. It is removed from a thin wire, inspected and cleaned. The gas tank is washed with gasoline.
• Sapun. In the gas tank, a vacuum is created during fuel suction, and fuel does not work well or does not come at all. This part cannot be repaired. Most often, the sapun is located in an inaccessible place, at the outlet of the fuel line from the gas tank. It is changed to a new.

Иногда вместо ремонта сапуна проделывают отверстие в крышке бензобака диаметром 0,2-0,5 мм. The downside is that gasoline can flow through the hole during operation, and after operation the chainsaw can only be placed on the side, the gas tank lid is upward.

How are things with reptiles

The reptile can be bought at the same retail outlets where carburetors are also sold. They are sold in two types of configuration:

It is difficult to find other spare parts in a separate form.

Carburetor cleaning and all about it: Useful tips

You are already oriented: what is the cleaning of the carburetor of the chainsaw. We have painted all the nuances and trifles, and now in the resume we will consider other options for breakdown or faulty tools of the tool, accompanying clogging of the carb, which also need to be paid attention to:

• The failure of the rubber adapter. When it breaks through, the chainsaws gives the same non.working signs as with a clogged carburetor. It is located between the cylinder and the carb;
• You can hear its name and as a pipe. The chrome of this that the carburetor is clogged in the saw, the pipe can rotate;
• It will not be enough to clean the carb, you will have to change the rubber adapter. Our catalog will help to do this easily;
• The fuel filter fixer can be cracked or broken, respectively, all the dirt enters the carburetor;
• A crab grid can be clogged, which should clean gasoline, which passes from the tank to the needle;
• Do not forget to fix the number of revolutions on which the screws “h” and “l” were twisted. Adhering to their competent return to your place. you will save the settings of the carburetor, but this is a completely different article.

Necessary tools

Professor Bright Husqvarna.based tools for configuring the carburetor of the Chinese chainsaw. this is a slotted screwdriver (flat type) of medium size. Some saws require special keys, for example, to configure Khuskvarna.

For a more accurate and quick setup, a tachometer is still required, it allows you to determine the engine speed, but this is not our case, our task is to learn how to configure by ear.

In more detail about what tachometers are, where to buy, how much it costs, and also, how to use it to configure a chainsaw, read here.

For reference! This is also that the tuning of the guitar. An experienced musician sets up by ear, and a beginner using special instruments. In the case of a chainsaw, the opposite. Experienced tunes with a tachometer, and a beginner by ear. In our repair workshop, we use a high.quality and inexpensive tachometer with Aliexpress, which can be bought at this link.

Adjustment of the carburetor of the chainsaw STIHL 180

Usually, special screws are responsible for the quantity and quality of fuel diffuser, the adjustment of which we change the cross section of the fuel channel. But on the Stihl 180 chainsaw used, to facilitate the operation of the saw, these two screws are missing.

The channels are designed so that the optimal amount of fuel falls into the diffuser at all engine speeds. And for adjustment, the LD screw is responsible here, the rotation of which is adjusted the air supply to the idle nozzle. Due to which there is a change in engine speed.

So, to adjust the Carburetor of the Stihl 180 chainsaw, an ordinary flat screwdriver and electronic tachometer (not necessarily) will be needed. The adjustment algorithm is as follows:

• Check the air filter. If necessary, replace the filter element.
• Twist the LD screw counterclockwise to the end, and then unscrew by 2 turns. Attention, left thread! For access to the screw on the saw housing, a hole for the screwdriver is provided. Run the engine and warm up for 5-7 minutes.
• Turning the LD screw slowly clockwise, we arbitrarily set up idle. 2 situations are possible: the number of engine speeds at idle is very small. The engine does not hold idle. We turn the LD screw until it starts to rotate, and then we turn the screw 1/2 ago (the chain should stop).
• The saw is spinning at idle. In this case, slowly turn the screw counterclockwise until the circuit stops, then turn the screw by another 1/2 turn in the same direction.

If after all the manipulations with the carburetor settings, the chain continues to spin at idle, the saw should be given to the dealer to the service center.

Below the video shows a detailed adjustment of the Carburetor of the Stihl 180 chainsaw using an electronic tachometer.

Repair of the carburetor of the chainsaw STIHL 180

The main malfunctions of the Carburetor of the Stihl 180 chainsaw can be attributed to the following.

• Gasoline does not enter the carburetor. The banal reason is the refusal of the fuel pump. The diaphragm has lost its elasticity or leaked. This happens due to fatigue of the material with prolonged use. As a result, when the diaphragm does not rise in the engine, the fuel channel with the valve does not open in the engine. It can be replaced by a spare from the reprimatum, having disassembled the carburetor.
• Gasoline may also not arrive due to the clogged filter element (nets) in the channel between the fuel pump and the needle valve. It is also treated by replacement from the reptile.
• The carburetor shifts. It is not difficult to guess that the problem lies in the main chamber. Particles of dirt fall into the cavity between the needle and the channel, t.e. The valve does not completely cover the channel when it is necessary and fills the camera. Very often the membrane ceases to perform its functions due to stretching (natural wear). As a result, when lowering the membrane, it does not completely raise the needle, and the fuel continues to arrive. The main membrane is also part of the remote complex. It will not be difficult to replace it.
• Very often after winter downtime, the owners of the chainsaw of Stihl 180 are faced with a difficult launch. In this case, there is a sticking valve in the nozzle. The manufacturer recommends that the remaining gasoline in the carburetor be laid down before putting the chainsaw. Gasoline is prone to evaporation and with long storage, motor oil remains in the carburetor, when in contact with which the nozzle valve begins to stick to the case. As a result, the fuel does not enter the diffuser. Since the nozzle is not part of the remote complex, you have to knock it out and rinse thoroughly. You need to do this very carefully.
• If the nozzle nozzle or nozzle is clogged, it is enough to blow them with compressed air. Or rinse in gasoline, in 90 % of cases it helps. But you can not use needles or wires, t.to. There is a risk of changing the passing cross section, thereby changing the throughput of the jet of jackets.

The common problem is due to which the STIHL 180 is unstable-this is the loss of a locking ring on the axis of the throttle, as a result, it begins to hang out and wrap up, which in turn leads to interruptions in work.

So, you decided to remove the carburetor and diagnose. The removal procedure is as follows:

• Click the gas trigger and lower the leaks lever down. Turn the latch and remove the chainsaw cover.
• We unscrew the 8.mounted fasteners with a end key and remove the air filter with the case.
• Remove the thrust of gas (throttle) carburetor.
• Disconnect the cable from the control lever
• We take out the engine control lever from our place. In parallel, disconnect the thrust of the air damper.
• Pulling the carburetor on ourselves, we remove it from the stilettos. Do not forget to disconnect the fuel supply hose.

A more detailed and visual algorithm for dismantling the carburetor from the chainsaw is presented in the video.

As for disassembling the carburetor of the Stihl 180 chainsaw, then everything is simple. 1 bolt is unscrewed on the lid of the fuel pump and 4 bolt on the lid of the main chamber. This is enough to change all the necessary components from the remote complex.

After disassembly, the carburetor must be washed in gasoline, and the channels and nozzles should be blown with compressed air. In no case should you blow the carburetor under high pressure and in the collected state. Otherwise you can stretch the membrane or diaphragm. The carburetor will stop working properly.

In order to evaluate the condition of the mesh-filter and membrane, you need to perform the following sequence of actions:

Under the membrane everything should be clean

There should also be no dirt on the membrane

Total need to unscrew 4 screws

As for the stihl 180 carburetor remote control, it includes a set of gaskets for covers, aperture and a membrane, a needle valve, a rocker with an axis and a spring.

How to determine the malfunction of the carburetor of the chainsaw?

When operating the chainsaws, you should be careful about the appearance of extraneous sounds, smells and vibrations, since this can be a signal of a carburetor malfunction. Even if the tool began to stall periodically, this already indicates the need for repair work.

Signs of a carburetor malfunction, which should first pay attention to:

• The engine starts up difficult and stalls almost immediately.
• Gasoline consumption is disproportionate, fuel in the cylinder does not burn completely, a thick exhaust is characteristic.
• The factory settings of the carburetor were violated due to unsuccessful attempts to regulate or vibration.
• The air cleaning system is faulty, which provokes the entry of garbage particles into the fuel part of the tool.
• The piston group is worn out (the replacement of worn parts is required).

Of course, setting up the carburetor will not save all problems. For example, when the garbage particles gets first, it is necessary to rinse the fuel part of the engine, and with wear of the piston group, replace obsolete or faulty parts. However, in some cases, it is the adjustment of the carburetor of the chainsaws that will extend the time frame of the instrument service before major repairs.

How to adjust the carburetor on a chainsaw correctly?

In order for the independent setting of the carburetor of the chainsaw to bring the desired result, you need to carry out preparatory work. First of all, the operator must make sure that the engine is about the service. To do this, it is necessary to remove the top cover of the protective plastic case and carefully inspect the engine CPG for the presence of burrs, cracks and other defects. If they formed, then the surface of the node will need to be polished. At the same time, it is important not to damage the protective chrome or Nikasil coating of the cylinder.

Next, you need to inspect the spark plug. In the case of the formation of a thick layer of dried up on it, the part will need to be twisted and carefully cleaned. To do this, you need to heat the candle and gently scrape off the remains of dried oil from its tip.

At the end, you will need to inspect the details of the entire fuel system of the chainsaw. The clogging in the tubes, the accumulated garbage in the fuel and air filters, the unstable work of the diffuser. all this leads to the engine loss of the necessary revolutions. As a result, the operator does not receive accurate information about the operation of the motor and cannot set the correct settings. To prevent this, you need to rinse the parts of the carburetor, filter and tube. After they are completely dry, they can be installed in the original place.

DIY Disassembly: nothing complicated

First of all, you need to prepare a place for disassembly. It can be a workbench or ordinary table. In addition, you need a rectangular piece of fabric or cardboard. on it you will carefully fold the parts of the carburetor. And finally, the tool: for disassembly, you will need a set of core worships and screwdrivers, a special cleaning composition and an ultrasound cavitation bath.

Tool for repairing a chainsaw carburetor

At first you will have to dismantle the gasopil carburetor. This is done in this order:

To get to the carburetor, you need to remove the top cover of the chainsaw recorded by three bolts.

Removing the fuel hose and drive traction

After removing the gasoline hose, the carburetor is ready for disassembly

The disassembly of the carburetor must be performed in the manner prescribed by the design and functional solutions of its elements. The details of the carburetor of the chainsaws do not differ in dimensions, so you need to fold them carefully and in order, trying not to lose anything.

Dismantling the carburetor of the chainsaw in the photo

After disassembly, it is necessary to conduct a defect and replace damaged or worn parts. Next, the whole kit should be washed with a special tool, dry and wiped with a dry bezor cloth. The jackets and tubes of the node must be blown with compressed air, or, in order to more thoroughly remove formations on their internal surfaces, before this, treated with ultrasound.

Carburetor Settings: Basic points

Refract assembly of the carburetor is carried out only after complete cleaning, drying and purging with compressed air. At the same time, do not forget that some gaskets and seals, even if there are no damage, must be replaced.

You can start adjusting the carburetor, provided that it is properly defective, high.quality assembly and impeccable reverse installation on the engine.

Carburetor configuration principles:

• screws n and l are regulated by the ratio of air and combustible mixture, t.e. The position of the throttle. Twisting the screws clockwise leads to the impoverishment of the mixture and the transition of the motor to low speeds. When unscrewing (counterclockwise), the mixture is enriched, and engine speeds grow;
• The screw T is responsible for adjusting the idle speed: turning it clockwise gives an increase in their number, against a decrease;
• screws are adjustable in order l-h-t.

The general adjustment algorithm looks something like this:

• At first, the largest idle revolutions are by turning the screw l with subsequent return to ¼ turn counterclockwise. If the chain rotates in idle, turn the screw t in the same direction to its complete stop.
• With a heated engine operating at full speed, rotate the screw N by ¼ turn to the left, and then let the engine 10 with work check the indicator of the maximum revolutions using a tachometer. He must meet the figure specified in the tool passport.
• After calibration with screws l and n using the screw t, the idle speed is set up. If everything is done correctly, the engine will work evenly in all its positions.

Memos for the potassium carburetor potassium on the chainsaw building

Upon completion of the adjustment, it remains to install the chainsaw cover with the insulating gasket, after which you can start the main job. If the settings are correct, the chainsaw engine will receive the optimal fuel mixture. This will provide its normal efficiency, as well as general comfort and safety of working with the tool.

The design and principle of the carburetor of the chainsaw

The carburetor of the chainsaw consists of the following main nodes:

• a whole body made of light aluminum alloy;
• diffuser located at the entrance to the carburetor;
• nozzles, special valves designed to adjust the supply of a combustible mixture;
• sprayer;
• float chamber.

Below is the scheme of the carburetor of the company WALBRO, which very often equipped chainsaws. Using this scheme, you can study in more detail the internal device of the carburetor of the chainsaw.

The carburetor can have 2 or 3 adjusting screws with springs. Adjusting screws are designed so that at their endings there are needles (cones). The screws have the right thread, that is, twist clockwise.

The operation of the gasopyle carburetor is as follows.

• After the launch of the ICE, the air damper opens.
• In diffuser (16), where there is a narrowing, the air flow is accelerated and mixed with gasoline. The latter enters the nozzle (15) and (12), and the air peeled by the air filter. through the damper (7) located at the inlet of the diffuser.
• The damper (8), located behind the diffuser, regulates how much the cooked mixture will fall into the combustion chamber.
• The volume of gasoline passing through the nozzles is regulated by screws (17) and (10). this is, respectively, the screws L and H on a chainsaw.
• The volume of the fuel mixture in the float chamber (14) depends on the needle valve (11). The functioning of the needle valve is controlled by the membrane (13).
• The membrane (4) controls the supply of the fuel mixture into the combustion chamber, and it depends on the number of ICE revolutions. Gasoline is cleaned through the filter (6).

The malfunction of the circuit carburetor

Remove the carburetor from the chainsaw. Remove the gas pump lid using the diaphragm, unscrewing one screw in the center of the lid. Then turn the carburetor to yourself with the help of a throttle, from the side where there are two holes, in one pin is visible, here there is an accelerating pump under it. Remove the locking ring with the outer side of the pin and disconnect the air damper of the wire spring. Unscrew the screw in the center of the throttle, remember how the throttle is installed (and then put it) and remove the throttle. A hole for a finger pin (the accelerator is springy, and if you pull out the shaft of the throttle and do not close the hole, then the accelerator will pop up), then turn the shaft of the throttle and remove it. Shake the accelerator (piston) with a spring from the hole. There is a rubber cuff (ring) on ​​the piston). Its wear is the cause of the chainsaw malfunction. rubber cuff and spring (they are sold as a repair kit). Or you can remove a worn piston with a spring and plug the hole, scoring a rubber plug (the chainsaw will be without an accelerating pump, t. E. It will not accelerate for 3 seconds, but for 4 seconds, but it will work well because there will be no carburetor suction).

Assembly after repairing a malfunction of the chainsaw (after removing the malfunction of the carburetor chain saw) is performed in the reverse sequence of disassembly. When assembling the throttle, before screwing the screw, the throttle should be correctly located so that it does not stick, and screw the throttle screw on the axis, degrease and lay out with a special sealant for thread (sold in small pipes, red. fluid) or pliers, because if this bolt comes out during operation, it goes directly to the cylinder), and the repair or replacement of the piston cannot be avoided). Therefore, we examined the elimination of this malfunction of the chainsaw.
