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 caF The limiter cap
cannot be removed without breaking the
adjusting needler
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:
tn general, turning idle mixture valve in
(clockwise) decreases the supply of fuel to
the engine giving a leaner fuel/air 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 turned in too tight.
PRELIMINARY SETTING -

bled to the carburetor when making car-
buretor adjustments,

adjusted properly (see above).
FINAL SETTING

tion,, With finger, rotate and hold throttle
lever against idle speed screw, Turn
idle speed screw to attain 1750 RPM.
