TO ADJUST CARBURETOR
The carburetor has been present 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 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 -
1. 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).
