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, fuming idle mixture valve in (clockwise) decreases the supply of fuel to the engine gMng a leaner fuel/air mixture. Turning the idle mixture valve out (counter- clockwise) increases the supply of fuel to the engine gMng 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 -

making carburetor adjustments.
2.Be sure the throttle control cable is adjusted properly (see above).
FINAL
