TO ADJUST CARBURETOR
The carburetor has been preset at the
factory and adjustment should not be
necessary. However, minor adjustment
may be required to compensate for
differences in fuel, temperature, altitude
or load. If the carburetor does need
adjustment, proceed as follows:
In general, turning the mixture screw In
(clockwise) decreases the supply of fuel
to the engine giving a leaner fuel/air
mixture. Turning the mixture screw out
(counterclockwise) increases the supply
of fuel to the engine giving a richer fuel/
air mixture.
IMPORTANT: Damage to the needles
and the seats in carburetor may result if
screw is turned in too tight.
PRELIMINARY SETTING -
• Be sure you have a clean air filter, and
the throttle control cable and choke
are adjusted propedy (see above).
• With engine off turn idle mixture screw
27 in (clockwise) closing it finger tight and
