TO ADJUST CARBURETOR
NOTE: The carburetor on this engine is
low emission. It isequipped with an idle
fuel adjusting needle with a limiter cap,
which allows some adjustment within the
limits allowed by the cap. Do not attempt
to remove the limiter cap. The limiter cap
cannot be removed without breaking the
adjusting needle.
The carburetor has been preset at the fac-
tory and adjustment should not be neces-
sary. However, minor adjustment may be
required to compensate for differences in
fuel, temperature, altitude or load. Ifthe
carburetor does need adjustment, proceed
as follows:
In general, tuming idle mixture valve in
(clockwise) decreases the supply of fuel to
the engine giving a leaner fuel/air mixture.
Tuming the idle mixture valve out
(counterclockwise) increases the supply of
fuel to the engine giving a richer fuel/air
mixture.
IMPORTANT: Damage to the needle valve
and the seat in carburetor may result if
screw is turned in too tight.
PRELIMINARY SETTING -
• Air cleaner assembly must be assem-
bled to the carburetor when making car-
buretor adjustments.
• Be sure the throttle control cable is
adjusted propedy (see above).
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.
• Move throttle control lever to slow posi-
tion. With finger, rotate and hold throttle
lever against idle speed screw. Turn idle
speed screw to attain 1750 RPM.
• While stillholding throttle lever against
idle speed screw, turn idle mixture valve
full travel clockwise then counterclock-
wise untilengine rune rough. Tum valve
to a point midway between those two
positions. Release throttle lever.
