Spark Arrestor
Use the following procedure to periodically purge accumulated car-
bon from the exhaust system.
1. Loosen the set screw and remove the spark arrestor from the
muffler. Tap the arrestor on a hard surface to loosen carbon deposits
and clean the inside of the tubing.
2. Place the engine in neutral and start the engine. Purge the accu-
mulated carbon from the system by momentarily revving the engine
several times. Rap the exhaust system and repeat the procedure
several times to expel additional carbon.
3. Stop the engine and allow the exhaust system to cool.
4. Reinstall the spark arrestor.
