TO ADJUST CARBURETOR

The carburetor has been present at the factory and adjustment should not be necessary. 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 fuel/air mixture. Turning the adjusting needles out (countemlockwise) 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-rlNG-

1.Be sure you have a clean air filter, and the throttle control cable is adjusted properly (see "TO ADJUST THRO'I-I'LECONTROL CABLE" in the Service and Adjustments section of this manual).

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

FINAL SE'I-I'ING-

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

NOTE: The high idle is sat at the factory and cannot be adjusted.

2.Idle seeed settino - 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.

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

4.Recheck idle speed. Readjust if necessary.

ACCELERATION TEST -

5. Move throttle control lever from slow to fast position. If engine hesitates or dies, turn idle fuel adjusting needle out (counterclockwise) 1/8 turn. Repeat test and continue to adjust, if necessary, until engine accelerates smoothly.

High speed stop is factory adjusted. Do

not adjust-damagemay result. IMPORTANT: Ne_._r 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 quaJilied servicecenter, which has proper equip. ment and experience to make any necessary adjustments.
