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, pro- ceed as follows:
In general, turning the mixture screw in (clockwise) decreases the supply of fuel
PRELIMINARY
•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
•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 against idle
speed screw and adjust idle speed screw to obtain 1200 to 1400 RPM.
•While still holding throttle lever against idle speed screw, turn idle mixture screw in (clockwise) until engine begins to die and then turn out (counterclock- wise) until engine runs rough. Turn screw to a point midway between those two positions.
•Continue to hold throttle lever against
idle speed screw and adjust idle speed screw to obtain 900 to 1200 RPM. Re-
lease throttle lever.
ACCELERATION TEST -
•Move throttle control lever from slow to
fast position. If engine hesitates or dies, turn idle mixture screw out (counter- clockwise) 1/8 turn. Repeat test and continue to adjust, if necessary, until en-
gine accelerates smoothly.
High speed stop is factory adjusted. Do not adjust - damage may result.
IMPORTANT: Never tamper with the en- gine governor, which is factory set for proper engine speed. Overspeeding the engine above the factory high speed set- ting can be dangerous. If you think the en-
=ng, contactyour nearest authorized ser-
vice center/department, which has proper equipment and experience to make any necessary adjustments.
