TO ADJUST CARBURETOR

The carburetor has been present at the factory and adjustment should not be nec- essary. 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 mixtu re.

IMPORTANT: Damage to the needles and the seats in carburetor may result if screw is turned in too tight.

PRELIMINARY SETTING -

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

2.With engine off turn idle fuel adjust-

ing needle in (clockwise) closing it finger tight and then turn out (counter-

clockwise) 1 turn.

FINAL SETTING -

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 set at the factory and cannot be adjusted.

2.Idle speed 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 at- tained.
