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?

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.

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.
