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.
