thenturn out (counterclockwise)1-1/4
to 1-1/2turns.
FINAL SE'I-I'ING -
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
position, 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, tum idle mixture
screw In (clockwise) until engine
begins to die and then turn out
(countemlockwise) 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. Release throttle lever.
ACCELERATION TEST -
Move throttle control lever from slow to
fast position. If engine hesitates or
dies, turn idle mixture screw out
(counterclockwise) 1/8 turn. Repeat
test and continue to adjust, if neces-
sary, until engine accelerates
smoothly.
High speed stop is factory adjusted. Do
not adjust - damage may result.
IMPORTANT: Never tamper with the
engine governor, which is factory sat for
proper engine speed. Overspeeding the
engine above the factory high speed
setting can be dangerous. If you think the
engine-governed high speed needs
adjusting, contact your nearest autho-
rized service center/department, which
has proper equipment and experience to
make any necessary adjustments.
