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.
