TO ADJUST CARBURETOR (See Figs. 34 &

35)

The carburetor has been preset at the factory and adjust- rnent should not be necessary. However, minor adjust- rnent 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 mixture screw in (clockwise) de- creases the supply of fuel to the engine giving a leaner fuel/ air mixture. Turning the miXture screw out (counterclock-

wise) 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.
