SPARK ARRESTOR MAINTENANCE
1. Remove air filter/muffler cover. Refer to Removing the Air
Filter/Muffler Cover.

the engine (Fig. 36). Remove the two (2) bolts using a
flatblade screwdriver or 5/16-inch socket or nut driver.
Pull muffler off of the engine.
3. Turn muffler over to the back side and locate the exhaust
gasket. Remove the muffler gasket from the muffler (Fig. 36).
NOTE: If the exhaust gasket is torn or damaged, replace
it with a new gasket before reassembling muffler.
4. Using a small flatblade screwdriver, carefully pry up the
spark arrestor from the recessed hole (Fig. 37). Remove
the spark arrestor from the muffler.
5. Clean the spark arrestor with a wire brush. Replace it if it is
damaged or if it is impossible to clean thoroughly (Fig. 37).
6. Reinstall the spark arrestor by pressing it into the
recessed hole on the muffler's back side. Make sure it fits
tightly against the muffler and is not raised up.

Align the gasket bolt holes with the bolt holes in the
muffler. While holding exhaust gasket in place, insert the
bolts into the muffler's front side (Fig. 36).
8. Place the muffler (with the exhaust gasket in place and
bolts inserted), against the engine, aligning the bolt
holes. Tighten the bolts to secure the muffler to the
engine.
