Reinstalling the Air Filter/Muffler Cover

1.Place the air filter/muffler cover over the back of the carburetor and muffler. Align the screw holes.

2.Insert the four (4) screws into the holes in the air filter/muffler cover (Fig. 25) and tighten. Do not over-tighten.

SPARK ARRESTOR MAINTENANCE

NOTE: The exhaust can only flow in one direction: AWAY from the engine. Pay close attention when disassembling the muffler so you can put it back together correctly. Failure to do so will damage the unit and may cause serious personal injury.

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

2.Locate the muffler, but do not remove it. Find the one (1) screw on the bottom of the muffler (Fig. 30). These two screws hold the Spark Arrestor Hood Assembly and the spark arrestor screen to the bottom of the muffler. Remove the two

(2) screws using either a torx #20 or flat blade screwdriver.

3.Using a small flat blade screwdriver, carefully pry up the spark arrestor screen from the recessed hole, taking care to notice that the “raised” part of the spark arrestor screen is inside the recessed hole. Remove the spark arrestor screen from the muffler.

4.Clean the spark arrestor screen with a wire brush. Replace it if it is damaged, or if you are unable to clean it thoroughly.

5.Reinstall the spark arrestor screen by putting the “raised” por- tion of the screen inside the recessed hole of the muffler. Make sure that the spark arrestor screen fits flat against the muffler.

6.Place the spark arrestor plate on top of the spark arrestor with the “raised” side up and the opening facing towards the engine (Fig. 30).

7.Place the spark arrestor hood on top of the spark arrestor plate with the “raised” side up and the opening facing AWAY from the engine (Fig. 30). Verify that the exhaust will be directed AWAY from the engine.
