merit should notbe 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-
