6. Replace the air filter inside the air filter/muffler cover (Fig. 15).

NOTE: Operating the unit without the air filter and air filter/muffler cover assembly will VOID the warranty.

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. 14) and tighten. Do not over tighten.

SPARK ARRESTOR MAINTENANCE

NOTE: 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 (p. 9).

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” portion 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 screen with the raised side up and the opening facing toward the engine (Fig. 19)

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. 19). Verify that the exhaust will be directed AWAY from the engine.

8.Replace the screw you removed in Step 2 and tighten securely.

9.Reinstall the air filter/muffler cover (Fig. 14).

WARNING: If the spark arrestor hood and spark arrestor screen are not tightened securely, they could fall off causing damage to the unit and possible serious personal injury.

CARBURETOR ADJUSTMENT

The idle speed of the engine is adjustable through the air filter/muffler cover (Fig. 20).

NOTE: Careless adjustments can seriously damage your unit. Contact a Sears or other qualified service dealer to make carburetor adjustments. Call 1-800-4-MY-HOME®for more information.

Check Fuel Mixture

Old and/or improperly mixed fuel is usually the reason for improper unit performance. Drain and refill the tank with fresh, properly-mixed fuel prior to making any adjustments. Refer to Oil and Fuel Information (p. 6).

Clean Air Filter

The condition of the air filter is important to the operation of the unit. A dirty air filter will restrict air flow and change the air/fuel mixture. This is often mistaken for an out of adjustment carburetor. Check the condition of the air filter before adjusting the idle speed screw. Refer to Air Filter Maintenance (p. 9).
