SPARK ARRESTOR MAINTENANCE

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

2.Locate muffler front and the two (2) bolts securing it to the engine (Fig. 52). 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. 52).

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. 53). 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. 53).

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.

7.Place the exhaust gasket against muffler's back side. 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. 52).

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.

If using a torque wrench, torque to:

80-90 in.•lb. (9-10.2 N•m)

9.Reinstall the air filter/muffler cover.
