CARBURETOR ADJUSTMENT
The idle speed of the engine is adjustable. An idle
adjustment screw is reached though a hole in the top of
the engine cover (Fig. 40).
NOTE: Careless adjustments can seriously damage your
unit. An authorized service dealer should make
carburetor adjustments.
Check Fuel
Old fuel is usually the reason for improper unit
performance. Drain and refill the tank with fresh fuel prior
to making any adjustments. Refer to Oil and Fuel
Information.
