TO ADJUST CARBURETOR
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 limiter cap cannot be
removed without breaking the adjusting needle.
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, turning idle mixture valve in (clockwise) decreases the supply of fuel to the engine giving a leaner fueVair mixture. Tuming the idle mixture valve out (counter- clockwise) increases the supply of fuel to the engine giving a richer fueVair mixture. IMPORTANT: Damage to the needle valve and the seat in carburetor may result if screw is turned in too tight.
PRELIMINARY SETTING -
1.Air cleaner assembly must be assembled to the carburetor when making carburetor adjustments.
2.Be sure the throttle control cable is adjusted properly (see above).
FINAL SE'FI'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.
2.Move throttle control lever to slow position. With finger, rotate and hold throttle lever against idle speed screw.
Turn idle speed screw to attain 1750 RPM.
3.While still holding throttle lever against idle speed screw, turn idle mixture valve full travel clockwise then counterclock-
wise until engine runs rough. Turn valve to a point midway between those two positions. Release throttle lever.
ACCELERATION TEST-
4.Move throttle control lever from slow to fast position. If engine hesitates or dies, turn idle mixture valve out (counterclock- wise) 1/8 turn. Repeat test and continue
to adjust, if necessary, until engine accelerates smoothly.
High speed stop is factory adjusted. Do not adjust or 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
