Carburetor adjustment and configuration

The maximum and minimum engine speeds, even idle is regulated by the carburetor. The stable operation of the lawn mower depends on the amount of fuel mixture and air. The lawn mower is not started with disturbed adjustment of the carburetor. The procedure for setting up the device for supplying fuel at low speeds (L), high speeds (H) and idle (T) is regulated by the same vints:

  • The chainsaw should work for at least 10 minutes, since the adjustment is carried out in hot.
  • The screw n is flooded smoothly to maximum speed, then turning on ¼, counterclockwise, reducing the speed of rotation of the engine shaft.
  • The idle stroke is regulated by the screw T, ensuring that the braid for the grass does not rotate.
  • The screw l is regulated, first opening the throttle as much as possible, and then smoothly reducing the speed to stable minimum.

Today we’ll try to understand such issues as: why the chainsaw stalls with increasing speed, as well as at idle and at full. Consider the options for diagnosing and eliminating faults associated with this behavior of the Stihl 180 chainsaw.

Why is the chainsaw stall when you press the gas

Suppose a chainsaw work normally at idle, but with a sharp press on the gas stalls. What could be the reason? It is immediately clear that the matter is not in the ignition (lack of spark), t. To. With a malfunction of the ignition and the lack of a spark, the tool would simply not start. So the fuel system remains.

There are a lot of malfunctions of the fuel system and to determine the exact reason why the stihl 180 chainsaw is stalling when pressing gas, it is necessary to carry out its full diagnosis. We recommend reading about the common malfunctions of the Stihl 180 chainsaw and their elimination.

Checking the filter

The first thing you need to check is the fuel filter.

In some cases, a filter clogged with dirt, it is unable to pass through the fuel mixture through sufficient quantities.

Accordingly, a deficiency of fuel occurs in the system, which leads to the fact that when pressing the gas is pressed, the fuel burns out, and the new one still does not have time to act as a result of which the Stihl chainsaw is stalling.

Also, with a clogged fuel filter, there may be a noticeable drop in the power of the chainsaw at maximum speed, but this is with slight contamination.

Air filter

On the pages of the World Wide Web, you can find information that the chainsaw of the Stihl 180 can stall due to severe air filter pollution.

I would like to refute this not entirely correct information, and report that the STIHL carburetor MS 180 is equipped with a compensator, which is designed and installed in order to make the air of the STIHL 180 chainsaw, bypassing the contaminated air filter.

Of course, the power with a clogged air filter will fall a little, but it will definitely not stall. Another capacity may fall due to the wear of the piston, here the repair of the piston chainsaw of the Stihl MS 180 will already be required.


One of the reasons why the chainsaw does not develop momentum when pressing gas, but on the contrary, stall, these are malfunctions of the carburetor. Suppose the STIHL 180 saw worked properly, and then it was put for a long time and did not use it.

After it was brought up, and it works well on idle, and when you press the gas, it can stall. Why stalls? The reason for the sticking valve-comps of the carburetor. Of course, this is not 100%, but the probability of such a malfunction is high.

We recommend reading an article about the device and repair of the STIHL 180 carburetor.

In order to check the nozzle, you need to remove the carburetor and disassemble it. To remove, it is necessary to unscrew two nuts of fastening of the air filter and carburetor, then remove the air filter and the engine control lever, disconnecting the air damper control craving for the carburetor. Next, you need to pull the carburetor a little on yourself, and disconnect the fuel supply hose.

Having removed the carburetor, it needs to be blown and cleaned of dirt, only after that the carburetor can be promoted.

It is necessary to promote the cover of the main camera of the carburetor, this is the one on which a compensator is installed on top. Further with a bolt by 8 mm and a length of at least 50 mm. We knock out the valve.

After the nozzle is removed, you can blow it with a compressor. The valve must pass air in only one direction, if you can freely blow the valve in both directions, then it is faulty and it is necessary to replace it with a new. Assemble a chainsaw after the valve is repaired, it is necessary in compliance with the reverse sequence of disassembly.

Look clearly how the carburetor repair is repair, or rather how to correct the valve record from the carburetor case, you can watch the video.

Another frequent reason why the saw can stall with an increase in revolutions, air leaks to the carburetor.

It is possible to check this only by having a special tool, but it is worth noting that if preventive work with the carburetor has not been carried out for a long time, then you can install a new set of gaskets in the carburetor. In some cases, this helps to solve the problem with its depressurization.

Disassembled the carburetor to replace the gaskets, you need to carefully inspect its needle valve, press the rocker and control its raising.

Sometimes, especially after the stihl chainsaw stood for a long time with fuel in the carburetor, the needle can burn to the carburetor body and not perform its functions.

Simply put, the needle valve will not pass the fuel mixture. In this case, the saw will not work.

Why stalls idle

The first and most common cause of this malfunction is the wrong carburetor adjustment. You can adjust the idle speed yourself, for this you need to have a STIHL adjustment screwdriver, which comes with the unit. The adjusting hole is located on the right side of the STIHL 180 saw on the handle and is indicated by the symbols “-” and “”.

If the Stihl chainsaw does not hold turns and stalls at idle, you can almost 90% sure that it has violations in the system of the fuel pump, as a rule, it is an air leak into the crankcase through the lining of the pallet, or, much more often, through the seals crankshaft. The air leaks reduces or even completely stops the impulse, which is supplied through special channels to the fuel pump of the chainsaw. As a result of this, the Stihl 180 chainsaw does not receive the required amount of fuel and stalls at idle.

Diagnose, you can use a special device called a vacuummeter.
