TO ADJUST CARBURETOR

The carburetor has been preset at the fac- tory and adjustment should not be neces- sary. However, minor adjustment 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) decreases the supply of fuel to the engine giving a leaner fuel/air mixture. Tuming the mixture screw out (counter- clockwiSe) 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 tumed in too tight.

PRELIMINARY SETTING -

•Be sure you have a clean airfilter, and the throttle control cable and choke are adjusted properly (see above).

•With engine off turn idle mixture screw in (clockwise) closing it finger tight and then turn out (counterclockwise) 1-1/4 to 1-1/2 turns.

FINAL SE'I-I'ING-

•Stad engine and allow to warm for five minutes. Make final adjustments with engine running and shift/motion control lever in neutral (N) position.

•With throttle control lever in slow posi- tion, hold throttle lever against idle

speed screw and adjust idle speed screw to obtain 1200 to 1400 RPM.

•While still holding throttle lever against idle speed screw, tum idle mixture screw in (clockwise) until engine begins to die and then tum out (counterclock- wise) until engine runs rough. Turn screw to a point midway between those two positions.

•Continue to hold throttle lever against

idle speed screw and adjust idle speed screw to obtain 900 to 1200 RPM. Re-

lease throttle lever.

ACCELERATION TEST -

•Move throttle control lever from slow to fast position. If engine hesitates or dies, tum idle mixture screw out (counter° clockwise) 118 tum. Repeat test and continue to adjust, if necessary, until

engine accelerates smoothly.

High speed stop is factory adjusted. Do not adjust - damage may result. IMPORTANT: Never tamper with the engine govemor, which is factory set for proper engine speed. Overspeeding the engine above the factory high speed set- ting can be dangerous. If you think the engine-governed high speed needs adjusting, contact your nearest authorized service centerldepadment, which has proper equipment and experience to make any necessaryadjustments.
