Spark Arrestor
The exhaust pipe must be periodically purged of accumulated car-
bon as follows:
1. Remove the clean out plugs (1) located on the bottom of the
muffler as shown above.
2. Place the transmission in neutral and start the engine. Purge
accumulated carbon from the system by momentarily revving
the engine several times.
3. If some carbon is expelled, cover the exhaust outlet and rap on
the pipe around the clean out plugs while revving the engine
several more times.
When cleaning the spark arrestor, you must follow the safe-
guards listed below to avoid serious injury or death.
D

gine has been run because the exhaust system be-
comes very hot.

there are no combustible materials in the area when
purging the spark arrestor.
