NOTE: The carburettor adjustment needle(s) are equipped with plastic
cap(s) which prevent anticlockwise rotation from the original factory
adjustment. If your unit exhibits specific performance problem(s)
where the Trouble Shooting Section recommends an anticlockwise
needle adjustment and no adjustments have been made since original
purchase, the unit should be taken to a factory-authorised service
dealer for repair. In most cases, the needed adjustment is a simple
task for the factory-trained service representative.
