ENGINE

Maintenance, repair, or replacement of the emission control devices and systems, which are being done at the customers expense, may be performed by any non-road engine repair establishment or individual. Warranty repairs must be performed by an authorized engine manufacturer'ssen/ice outlet.

TO ADJUST THRO'n'LE CONTROL CABLE

The throttle control has been preset at the factory and adjustment should not be necessary. Check adjustment as described below before loosening cable. If adjustment is necessary, proceed as follows:

1.With engine not running, move throttle control lever from slow to choke position. Slowly move lever from choke to fast position.

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

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

4.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 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, fuming the adjusting needles in (clockwise) decreases the supply of fuel to the engine giving a leaner fueVair mixture. Turning the adjusting needles out (counter- clockwise) increases the supply of fuel to the engine giving a richer fuel/air 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 limlter cap cannot be

removed without breaking the adjusting needle.

1.Be sure 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 soeed 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 settina - With throttle control lever in slow position, tum 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 pos'_ons.

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

ACCELERATION TEST -

6.Move throttle control lever from slow to fast position. If engine hesitates or dies, tum 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 - 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 proper equip- ment and experience to make any necessary adjustments.
