TO ADJUST CARBURETOR

The carburetor has been preset at the factory and adjustment should not be necessary. However, minor adjustment may be required to compensate for differences in fuel, temperature, altitude or lead. 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 mixture. Tumiog the adjusting needles out (counter- clockwise) increases the supply of fuel to the engine giving a richer fueVair mixture. IMPORTANT: Damage to the needles and seats in carburetor may result if turned in too tight.

NOTE: The carburetor on this engine is low emission. It is equipped with an idle fuel adjusting needle with a limiter cap, which allows some adjustment within the limits allowed by the cap. Do not attempt to remove the limiter cap. The limber cap cannot be removed without breaking the adjusting needle.

1.Be sere you have a clean air filter and the throttle control cable is adjusted properly (see above).

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

3.Idle seeed 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 attained.

4.idle fuel needle setting - With threttle 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. Turn needle to a point midway between those two positions.

5.Recheck idle speed. Readjust if neces- sery.

ACCELERATION TEST-

6.Move threttle 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 setting can be dangerous. If you think the engine-governed high speed needs adjusting, contact a Sears or other qualified service center, which has probe equipment and experience to make any necessary adjustments.
