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
inserting a pencil or a 1/4" drill bit through beth 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, tuming the adjusting needles in (clockwise) decreases the supply of fuel to the engine gMng a leaner fuel/air 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 #miter cap, which allows some adjustment within the limits allowed by the cap. Do not attempt to remove the limiter cap. The limiter 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, tum idle speed adjusting screw in or out until correct idle is attained.
4.Idle fuel needle setting - With throttle control lever in slow position, rum 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.
5.Recheck idle speed. Readjust if neces- sen/.
