TO ADJUST THROI"FLE CONTROL CABLE

The throttle 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 throttle control lever from slow to choke posi-

tion. Slowly move lever from choke to fast position.

•Check to see if hole in throttle lever and hole in speed control bracket are aligned.

•If holes are not aligned, loosen cable clamp screw and align the holes by inserting a pencil or a 1/4" ddll bit through both holes.

•Pull throttle cable up to remove slack and tighten cable clamp screw. Remove alignment pencil or drill bit.

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 adjusting needles in (clockwise) decreases the supply of fuel to the engine giving a leaner fueVair mixture.

Turning the adjusting needles out (counterclockwise) increases the supply of fuel to the engine giving a richer fueVair

mixture.-,

•Be sure you have a clean air filter and the tl=vr_ttecontrol cable is adjusted properly (see above).

•Start engine and allow to warm for five

minutes. Make adjustments with engine running and shift/motion control lever in neutral (N) position.

•Idle speed setting - With throttle control lever in slow position, engine should idle at 1750 RPM. If engine idles too slow or fast, turn idle speed adjusting screw in or out until correct idle is at- tained.

•Idle fuel needle setting - With throttle control lever in slow position, turn idle fuel adjustment needle in (clockwise) until engine begins to die and then turn out (counterclockwise) until engine runs rough. Tum needle to a point midway between those two positions.

•Recheck idle speed. Readjust if neces- sary.

ACCELERATION TEST -

•Move throttle control lever from slow to

fast position. If engine hesitates or dies, turn idle fuel adjusting needle out (counterclockwise) 1/8 rum. 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 governor, 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 AUTHO- RIZED service center/department, which has proper equipment and experience to make any necessary adjustments.
