PROBLEM

POSSIBLE CAUSE

SOLUTION

 

 

 

Engine will not start:

1.Switch not ON.

 

2.No spark.

3.No fuel.

4.Flooded engine.

5.Starter rope pulls harder now than when new.

1.Move switch to ON.

2.Check spark. Remove spark plug. Reattach the spark plug cap and lay spark plug on metal cylinder. Pull the starter rope and watch for spark at spark plug tip. If there is no spark, repeat test with a new spark plug.

3.Push primer bulb until bulb until fuel is visible in the bulb. If fuel is not apparent, the primary fuel delivery system is blocked. Contact a servicing dealer. If primer bulb fills, engine may be flooded (see next item).

4.Remove spark plug. NOTE: Do not let gas spill on the ground. Move choke lever to “RUN” and pull starter cord 10 to 15 times. This will clear excess fuel from engine. Clean and reinstall spark plug. Pull starter three times with choke lever at “RUN”. If engine does not start, move choke lever to “CHOKE” and repeat normal starting procedure. If engine still fails to start, repeat procedure with a new spark plug.

Engine does not reach full speed and emits excessive smoke:

1.Oil / fuel mixture is incorrect.

2.Air filter is dirty.

3.Carburetor requires adjustment.

4.Spark arrestor screen is dirty.

1.Use fresh fuel and the correct 2-cycle oil mix.

2.Clean air filter, refer to “Replacing and Cleaning the Air Filter” earlier in this manual.

3.Turn “H” needle clockwise 1/16 turn. See Figure 12.

4.Contact a servicing dealer.

NOTE: The carburetor adjustment needle(s) are equipped with plastic cap(s) that prevents counterclockwise rotation from the original factory adjustment. If your unit exhibits specific performance problem(s) where the Trouble Shooting Section recommends a counterclockwise needle adjustment and no adjustments have been made since original purchase, the unit should be taken to a factory authorized service dealer for repair. In most cases, the needed adjustment is a simple task for the factory trained service representative.
