Why pours a candle on a Stihl 180 chainsaw?

The essence of this failure is problems with the carburetor. For repair, you will need to remove this element, as well as check its membrane. In working condition, the part must be not only intact, but also flexible. If the membrane is roughened, then it will need to be replaced.

Before reassembling the Stihl MS 180 carburetor, it must be cleaned of dust and carbon. To do this, use compressed air in the cylinder. After the unit has completely dried, it can be assembled and installed back onto the chainsaw.

What to do if oil does not flow to the Stihl 180 chainsaw chain?

To solve the problem, you will need to remove the tool handle, pull out the hose and clean it. After this, the hose must be installed back onto the saw, and grease the installation site with sealant.

Another reason why oil is not supplied is the blockage of the Stihl MS 180 pump. To remedy the situation, you will need to remove the pump and rinse it in clean gasoline. If this does not help, the part will need to be replaced.

Stihl 180 chainsaw stalls when you press the gas. How to solve the problem?

In this case, remove the fuel filter and rinse it with clean gasoline. If this does not help, then carefully check the factory air filter. If a large amount of garbage has accumulated in it, then it will need to be replaced with a new element.

What if the saw stalls idling?

If the Stihl MS 180 chainsaw stalls some time after starting in idle mode, this indicates a fuel pump failure. To verify this, you need to use a vacuum gauge. If the device showed a pump malfunction, then the mechanism will need to be replaced.

Another reason for the malfunction is the wear of the Stihl MS 180 oil seals. After using the saw for a long time, they lose their shape and elasticity, passing a large amount of fuel. In case of wear of the glands, they will need to be replaced.

A chainsaw is bad to start up in the cold. Repair

Most often, the cause of this malfunction is the initially incorrectly set gap between the ignition coil and the flywheel of the Stihl MS 180 chainsaw. In this case, you need to disassemble the tool and take measurements between the contacts and the flywheel.

If the clearance is greater than 0.2 mm, then it must be reduced with a pair of side screws. To do this, you need to insert a paper business card or pocket calendar between the flywheel and the standard ignition coil. After that, by turning the screws, the flywheel should be brought closer to the ignition coil so that they hold the business card. In the end, it remains to carefully remove the paper and assemble the saw.
