SOLUTION
IF THESE SOLUTIONS DO NOT SOLVE THE PROBLEM, CONTACT YOUR AUTHORISED SERVICE DEALER.
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 Troubleshooting 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.
