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 fac- tory and adjustment should not be neces- sary. However, minor adjustment may be required to compensate for differences in fuel, temperature, altitude or load. If the
carburetor does need adjustment, pro- ceed as follows:
In general, turning idle mixture valve In (clockwise) decreases the supply of fuel to the engine giving a leaner fuel/air mix- ture. Turning the idle mixture valve out
(counterclockwise) increases the supply of fuel to the engine giving a richer fuel/air mixture.
IMPORTANT: Damage to the needle valve and the seat in carburetor may re- sult if screw is turned in too tight.
PRELIMINARY SETIING
•Air cleaner assembly must be as- sembled to the carburetor when making carburetor adjustments.
•Be sure the throttle control cable is ad- justed properly (see above).
FINAL SEI-FING
•Start engine and allow to warm for five minutes. Make final adjustments with engine running and shift/motion control lever in neutral (N) position.
•Move throttle control lever to slow posi- tion. With finger, rotate and hold throttle lever against idle speed screw. Turn idle speed screw to attain 1750 RPM.
•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.
