Stihl MS 391 Problems and Solutions

some of the common problems with the Stihl MS 391 chainsaw and their solutions:

Problem 1: Engine won't start

• Solution: Check for spark. Remove the spark plug and ground it against the cylinder head. If you see a spark, then the spark plug is good. If you don't see a spark, then the spark plug is bad or the ignition system is not working properly.
• Solution: Check for fuel. Make sure that there is fuel in the tank and that the fuel line is not clogged. You can also try priming the carburetor by pumping the primer bulb several times.
• Solution: Check for compression. Remove the spark plug and crank the engine over. If you feel compression, then the engine is good. If you don't feel compression, then the engine may have a problem with the piston, rings, or cylinder.

Problem 2: Engine loses power

• Solution: Check the air filter. If the air filter is dirty, it will restrict airflow and cause the engine to lose power. Clean or replace the air filter as needed.
• Solution: Check the spark plug. A fouled or damaged spark plug can also cause the engine to lose power. Clean or replace the spark plug as needed.
• Solution: Check the carburetor. A clogged carburetor can also cause the engine to lose power. Clean or adjust the carburetor as needed.

Problem 3: Chainsaw keeps stopping

• Solution: Check the fuel mixture. If the fuel mixture is too rich or too lean, it can cause the chainsaw to keep stopping. Adjust the fuel mixture as needed.
• Solution: Check the air filter. If the air filter is dirty, it will restrict airflow and cause the chainsaw to keep stopping. Clean or replace the air filter as needed.
