Cleaning the Exhaust Port and Muffler
Depending on the type of fuel used, the type and amount of oil used, and/or your
operating conditions, the exhaust port and muffler may become blocked with carbon
deposits. If you notice a power loss with your gas powered tool, a qualified service
technician will need to remove these deposits to restore performance.
