factory and adjustment should not be nec-
essary. Check adjustment as described

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 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:
In general, turning 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 givirlg 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.
