MAINTENANCE AND LUBRICATION
Spark Arrestor
Use the following procedure to periodically purge accumulated carbon
from the exhaust pipe.
1. Remove the arrestor
clean-out plugs (1) located
on the bottom of the
muffler.
2. Place the transmission in
neutral and start the engine.
3. Purge accumulated carbon
from the system by
momentarily revving the
engine several times.
4. If carbon is expelled, cover or plug the exhaust outlet (2) and rap
on the pipe around the clean-out plugs while revving the engine
several more times.
5. If particles are still suspected to be in the muffler, elevate the rear
of the vehicle one foot higher than the front. Set the parking brake
and block the wheels. Make sure the vehicle is in neutral and
repeat steps 2 and 4.
6. If particles are still suspected to be in the muffler, drive the vehicle
onto the incline so the front of the vehicle is one foot higher than
the rear. Set the parking brake and block the wheels. Make sure
the vehicle is in neutral and repeat steps 3 and 4 until no more
particles are expelled when the engine is revved.
7. Stop the engine and allow the arrestor to cool.
8. Reinstall the arrestor plugs and remove the outlet cover or plug.
