NOTE: The carburettor adjustment needle(s) are equipped with plastic cap(s) which prevent anticlockwise rotation from
the original factory adjustment. If your product exhibits specic performance problem(s) where the troubleshooting section
recommends an anticlockwise needle adjustment and you have made no adjustments since the original purchase, take
the product to a factory authorised service dealer for repair. In most cases, the needed adjustment is a simple task for
the factory trained service representative.
