TO ADJUST CARBURETOR (See Fig. 34)

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 load. If the carburetor does need adjustment, proceed as follows:

tn general, turning idfe mixture valve in (clockwise) de- creases the supply of fuel to the engine giving a leaner fuel/ air mixture. Turning the idle mixture valve out (counter-

clockwise) increases the supply of fuel to the engine giving a richer fuel/air mixture.

iMPORTANT: DAMAGE TO THE NEEDLE VALVE AND

TH E SEAT IN CARBURETOR MAY RESULT IF SCREW IS TURNED tN TOO TIGHT.

PRELIMINARY SETTING

•Air cleaner assembly must be assembled tothe carbu- retor when making carburetor adjustments.

,Be sure the throttle control cable is adjusted properly (see above).

•With engine off turn idle mixture valve in (clockwise) closing it finger tight and then turn out (counterclock- wise) I full turn.
