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 limiter cap
cannot be removed without breaking the
adjusting
needle.
The carburetor has been preset at the
factory
and adjustment should not be
necessary.
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 fuel/air mixture.
Turning the idle mixture valve out (counter-
clockwise) 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.
