TO ADJUST CARBURETOR (See Fig. 34)
The carburetor has been present at the factory and adjust_ merit should not be necessary. However, minoradjustment
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 the adjusting needles in (clockwise) decreases the supply of fuel to the enginegiving a !eaner fuel/air mixture. Turning the adjusting needles OUt (coun-
terclockwise) increases the supply of fuel to the engine giving a richer fuel/air mixture.
IMPORTANT: DAMAGE TO THE NEEDLES AND THE
SEATS IN CARBURETOR MAY RESULT IF SCREW IS TURNED IN TOO TIGHT.
