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.
