Troubleshooting a Stihl Chainsaw That Won’t Start

If your Stihl chainsaw won’t start, there are a few things you can check to troubleshoot the problem.

Check the fuel tank:
Make sure that the fuel tank is full and that the fuel valve is open.

Check the spark plug:
Remove the spark plug and check to see if it is wet. If the spark plug is wet, it means that the engine is not getting spark. Clean the spark plug with a wire brush and reinstall it.

Check the air filter:
Remove the air filter and check to see if it is dirty. If the air filter is dirty, clean it or replace it.

Check the carburetor:
If the chainsaw still won’t start after you have checked the fuel tank, spark plug, and air filter, you may need to clean the carburetor.

To clean the carburetor, you will need to remove the carburetor from the chainsaw. Once the carburetor is removed, you can use a carburetor cleaner to clean the jets and passages. Be sure to follow the instructions on the carburetor cleaner carefully.

Once you have cleaned the carburetor, reinstall it on the chainsaw and try starting it again. If the chainsaw still won’t start, you may need to take it to a qualified service technician for further diagnosis and repair.
