SPARK ARRESTOR MAINTENANCE

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

3.Turn the muffler over to the back side and locate the exhaust gasket. Remove the muffler gasket from the muffler (Fig. 31).

NOTE: If exhaust gasket is torn or damaged, replace with a new gasket before reassembling muffler.

4.Using a small flatblade screwdriver, carefully pry up the spark arrestor from the recessed hole (Fig. 32). Remove the spark arrestor from 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. 32).

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 the muffler's back side. Align the exhaust gasket bolt holes with the bolt holes in the muffler. While holding the exhaust gasket in place, insert bolts into muffler's front side (Fig. 31).

8.Place the muffler (with the exhaust gasket in place and the bolts inserted) against the engine, aligning the bolt holes. Tighten the bolts to secure the muffler to the engine.

80-90 in.•lb. (9-10.2 N•m).

WARNING: If muffler is not tightened securely, it could fall off causing damage to the unit and possible serious personal injury.
