TO ADJUST CARBURETOR
NOTE: The carburetor on this engine is
low emission. It is equipped 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 limifer 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. If the
carburetor does need adjustment, proceed
as follows:
In general, turning idle mixture valve in
(clockwise) decreases the supply of fuel to
the engine giving a leaner fueVair mixture.
Turning 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 tumed in too tight.
PRELIMINARY SE'I-I'ING
• Air cleaner assembly must be assem-
bled to the carburetor when making car-
buretor adjustments.
• Be sure the throttle control cable is
adjusted properly (see above).
FINAL SETTING
• Start engine and allow towarm forfive
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 holdthrottle
lever against idle speed screw. Turn
idle speed screw to attain 1750 RPM.
_, While stillholdingthrottle lever against
idle speed screw,turn idle mixturevalve
full travel clockwisethen counterclock-
wise untilengine runs rough. Tum
valve to a point midway between those
two positions. Release throttlelever.
ACCELERATION TEST
• Move throttle control lever from slow to
fast position. If engine hesitates or dies,
tum idle mixture valve out (counter-
clockwise) 1/8 turn. 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 factory high speed set-
ting can be dangerous. If you think the
engine-govemed high speed needs
adjusting, contact your nearest authorized
service center/department, which has
proper equipment and experience to make
any necessary adjustments.
