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
mixtu re.
IMPORTANT:
Damage to the needles
and the seats in carburetor may result if
screw is turned in too tight.
PRELIMINARY

the throttle control cable is adjusted

ing needle in (clockwise) closing it
finger tight and then turn out (counter-

2. Idle speed setting - With throttle control
lever in slow position, engine should
idle at 1200 RPM If engine idles too
slow or fast, turn idle speed adjusting
screw in or out until correct idle is at-
tained.
3. Idle fuel needle setting - With throttle
control lever in slow position, turn idle
fuel adjusting needle in (clockwise)
until engine speed decreases and then
turn out (counterclockwise)
approxi-
mately 3/4 turn to obtain the best low
