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, tuming the adjusting needles
in (clockwise) decreases the supply of fuel
to the engine giving a leaner fuel/air mix-
ture. 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 tumed in too tight.
PRELIMINARY
SETTING
-
• Be sure you have a clean air filter, and
the throttle control cable is adjusted
properly (see "TO ADJUST THROI-I'LE
CONTROL
CABLE" in the Service and
Adjustments section
of this manual).
• With engine off turn idle fuel adjusting
needle in (clockwise) closing it finger
tight and then turn out (counterclock-
wise) 1 tum.
FINAL SE'I-rlNG
-
• Start engine and allow to warm for five
minutes. Make final adjustments with
engine running and shift/motion control
lever in neutral (N) position.
• The high idle is set at the factory and
cannot
be adjusted.
• Idle speed _ettina - With throttle control
lever in slow position, engine should
idle at 1200 RPM. If engine idles too
slow or fast, tum idle speed adjusting
screw in or out until correct idleis
attained.
• Idle fuel needle settina - With throttle
control lever in slow position, tum idle
fuel adjusting needle in (clockwise) until
engine speed decreases end then tum
out (counterclockwise) approximately
314 tum to obtain the best low speed
performance.
• Recheck idle speed. Readjust if neces-
sary.
ACCELERATION
TEST -
• Move throttle control lever from-Slow to
fast position. If engine hesitates or dies,
tum idle fuel adjusting needle out
(counterclockwise)
1/8 tum. Repeat test
and continue to adjust, if necessary,
until engine accelerates smoothly.
High speed stop is factory adjusted. Do
not adjust-damage
may result.
IMPORTANT:
Never tamper with the
engine governor, which is factory set for
proper engine speed. Overspeeding
the
engine above the facory
high speed set-
ting can be dangerous.
If you think the
engine-governed
high speed needs
adjusting, contact your nearest authorized
service center/department,
which has
proper equipment and experience to make
any necessary adjustments.
