My Stihl fs160 keeps dropping power in the process of running. What could be the problem?


Here are a few things to check:

It could be the exhaust outlet is blocked with carbon deposits.

Remove exhaust and check and scrape away carbon if necessary.

It may also be dirt in the carburetor. Remove the carburetor and clean. Clean or change gaskets and diaphragm if necessary.

Check your fuel lines are clear and clean.

Check your fuel tank filter is clean.
