SOLUTION
IF THESE SOLUTIONS DO NOT SOLVE THE PROBLEM CONTACT YOUR AUTHORIZED SERVICE 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.
