POSSIBLE CAUSE

SOLUTION

 

 

 

Engine will not start:

1.No spark.

2.No fuel.

3.Flooded engine.

4.Starter rope pulls harder now than when new.

1.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.

2.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).

3.Remove spark plug, turn blower so spark plug hole is aimed at 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 start- ing procedure. If engine still fails to start, repeat procedure with a new spark plug.

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 pur- chase, the unit should be taken to a factory authorized service dealer for repair. In most cases, the needed adjust- ment is a simple task for the factory trained service repre- sentative.
