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.
