• Idle fuel needle setting - With throttle
control lever in slow position, turn idle
fuel adjustment needle in (clockwise)
until engine begins to die and then
turn out (counterclockwise) until
engine runs rough. Turn needle to a
point midway between those two
positions.
• Recheck idle speed. Readjust if
necessary.
ACCELERATION TEST -
• Move throttle control lever from slow to
fast position. If engine hesitates or
dies, turn idle fuel adjusting needle
out (counterclockwise) 1/8 turn.
Repeat test and continue to adjust, if
necessary, 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 set 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.
