Exhaust

The exhaust system is a frequently overlooked component of an engine. It is important to make sure the muffler
is in good condition and free of debris and/or insects.
NOTE: A blocked muffler will result in poor performance. If a muffler is completely blocked, the engine may not
start.
Spark arrestor (if equipped)
A spark arrestor, part #951-12329, is available as an
option.
NOTE: Spark arrestors are an option that are required on
all engines used in California and U.S. national
parks.
See Figure 8.1.
The spark arrestor also serves to keep blockages out of
the exhaust system.
NOTE: Typical blockages include insect nests built during
the dormant season.
The spark arrestor should be checked and/or cleaned
every month. The spark arrestor can be inspected by shin
-
ing a flash light into the muffler. See Figure 8.1.

10mm wrench and lift it off of the engine.
