TO ADJUST CARBURETOR
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, proceed as follows:
In general, turning the mixture screw in
(clockwise) decreases the supply of fuel to the engine giving a leaner fuel/air mixture.
Turnin_ the mixture screw out (counter- clockwzse) increases the supply of fuel to the engine giving a richer fuel/air mixture. IMPORTANT" Damage to the needles and the seats in carburetor may result if screw is turned in too tight.
PRELIMINARY SETTING
•Be sure you have a clean air filter, and the throttle control cable and choke are
adjusted properly (see above).
•With engine off turn idle mixture screw in (clockwise) closing it finger tight and
then turn out (counterclockwise)
FINAL SETTING
•Start engine and allow to warm for five minutes. Make final adjustments with
engine running and shift/motion control lever in neutral (N) position.
•With throttle control lever in slow posi-
tion, hold throttle lever a_ainst idle speed screw and adjust idle speed screw to obtain 1200 to 1400 RPM.
