STOP
Note: The carburetor adjustment needle(s) are equipped with
plastic cap(s) that prevent counterclockwise rotation from the
original factory adjustment. If your product exhibits specific
performance problem(s) where the Troubleshooting Section
recommends a counterclockwise needle adjustment and you
have made no adjustments since the original purchase, take
the product to a factory authorized service center for repair. In
most cases, the needed adjustment is a simple task for the
factory trained service representative.
