TO ADJUST CHOKE CONTROL

The choke control has been preset at the factory and adjustment should not be nec-

essary, check adjustment as described below before loosening cable. If adjust-

ment is necessary, proceed as follows:

•With engine not running, move choke control (located on dash panel) to full choke position.

•Remove air cleaner cover, filter and car- tridge plate to expose carburetor choke (See "AIR FILTER" in the Customer Re- sponsibilitiessection of this manual).

•Choke should be closed. If it is not, loosen casing clamp screw and move choke cable until choke is completely closed. Tighten casing clamp screw se- curely.

•Reassemble air cleaner.

TO ADJUST CARBURETOR

The carburetor has been present at the factory and adjustment should not be nec- essary. However, minor adjustment may be requiredto 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 engine giving a leaner fuel/air mix- ture. Turning the adjusting needles out (counterclockwise) 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.

PRELIMINARY SE'I-FfNG -

•Be sure you have a clean air filter, and the throttle control cable is adjusted

properly (see "TO ADJUST THROTTLE CONTROL CABLE" in the Service and

Adjustments section of this manual).

•With engine off turn idle fuel adjusting needle in (clockwise) closing it finger tight and then turn out (counterclock- wise) 1 turn.

FINAL SETTING -

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

•The high idle is set at the factory and cannot be adjusted.

•Idle sDeed settina - With throttle control lever in slow position, engine should idle at 1200 RPM. If engine idles too

slow or fast, turn idle speed adjusting screw in or out until correct idle is

attained.

•Idle fuel needle settina - With throttle control lever in slow position, tum idle fuel adjusting needle in (clockwise) until engine speed decreases and then turn out (counterclockwise) approximately 3/4 turn to obtain the best low speed performance.

•Recheck idle speed. Readjust if neces- sary.

ACCELERATION TEST -

•Move throttle control lever from slow to fast position. If engine hesitates or dies, tum idle fuel adjusting needle out (counterclockwise) 1/8 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 tamperwith 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-govemedhigh speed needs adjusting, contact your nearest authorized service center/department, which has proper equipment and experience to make any necessary adjustments.
