CAUSE

SOLUTION

 

 

 

Engine will not start:

1. No spark

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.No fuel

3.Flooded engine

4.Starter rope pulls harder now than when new

2.Push primer 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 starting 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 prevent counterclockwise rotation from the original factory adjustment. If your unit exhibits specific performance problem(s) where the Troubleshooting 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.
