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 specific 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.
