TO ADJUST CARBURETOR
The carburetor has been present at the
factory and adjustment should not be nec-
essary. 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 adjusting needles
in (clockwise) decreases the supply of
fuel to the engine giving a leaner fuel/air
mixture. Turning the adjusting needles 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 is adjusted
properly (see "TO ADJUST THROTTLE
CONTROL CABLE" in the Service and
Adjustments section of this manual).
