The exhaust system must be periodically purged of accumulated
carbon. To purge the system:
1. Select a well-ventilated area free of combustible materials and
make sure the exhaust pipe is cool.
2. Remove the bolt (1).
3. Start the engine and rev it up approximately twenty times while
momentarily creating exhaust system back pressure by blocking
the end of the muffler with a shop towel.
4. Stop the engine and allow the exhaust pipe to cool.
5. Reinstall the bolt securely.
