TO ADJUST CHOKE CONTROL

The choke control has been preset at the factory and adjustment should not be necessary, check adjustment as de- scribed below before loosening cable. If

adjustment is necessary, proceed as follows:

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

2.Remove air cleaner cover, filter and cartddge plate to expose carburetor choke (See "AIR FILTER" in the Maintenance section of this manual).

3.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 securely.

4.Reassemble air cleaner.

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 (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-rlNG-

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

properly (see "TO ADJUST THRO'I-FLECONTROL 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 end then turn out (counterclock- wise) 1 turn.

FINAL SETI'ING -

t.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 set at the factory and cannot be adjusted.

2.Idle sceed setting - 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.Idl_: fuel needle settine - With throttle control lever in slow position, turn idle fuel adjusting needle In (clockwise) until engine speed decreases end then turn out (counterclockwise) 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) t/8 turn. 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 Sears or other qualified servicecenter, which has proper equip- ment and experience to make any necessary adjustments.
