TO ADJUST CARBURETOR (See Fig. 33)
The carburetor has been preset at the factory and adjust-
ment should not be necessary_ However, minor adjust-
ment may be required to compensate for differences in fuel,
temperature, altitude or toado If the carburetor does need
adjustment, proceed as follows:
tn general, turning lhe adjusting needles in (clockwise)
decreases the supply of fuel to the engine giving a leaner
fuel/air mixture Turning the adjusting needles out (counter-
clockwise) increases the supply of fuel to the engine giving
a richer fuel/air mixture.

SEATS IN CARBURETOR MAY RESULT IF NEEDLE IS
TURNED IN TOO TIGHT

l imiter cap cannot be removed without breaking the adjusting
needle
