TO ADJUST CHOKE CONTROL
The choke control has been preset at the
factory and adjustment should not be nec-
essary, check adjustment as described
below before loosening cable. If adjust-
ment is necessary, proceed as follows:
• With engine not running, move choke
control (located on dash panel) to full
choke position.
• Remove air cleaner cover, filter and car-
tridge plate to expose carburetor choke
(See "AIR FILTER" in the Maintenance
section of this manual).
• Choke should be closed. If it is not, loosen
casing clamp screw and move choke
cable until choke is completely closed.
Tighten casing clamp screw securely.
• Reassemble air cleaner.

TO ADJUST CARBURETOR
The carburetor has been present at the
factory and adjustment should not be nec-
essary. 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 adjusting needles in
(clockwise) decreases the supply of fuel to
the engine giving a leaner fuel/air mixture.
Turning the adjusting needles out (coun
terclockwise) increases the supply of fue
to the engine giving a richer fuel/air mix
ture.
IMPORTANT: Damage to the needles an,
the seats in carburetor may result if screv
is turned in too tight.
PRELIMINARY SETTING -
• Be sure you have aclean air filter, and th,
throttle control cable is adjusted properl!
(see "TO ADJUSTTHROTTLE CONTROl
CABLE" in the Service and Adjustment_
section of this manual),
• With engine off turn idle fuel adjustin_j
needle in (clockwise) closing it fingel
tight and then turn out (counterclock-
wise) 1 turn.
FINAL SETTING -
• Start engine and allow to warm for five
minutes. Make final adjustments with
engine running and shift/motion centre
lever in neutral (N) position.
• The high idle is set at the factory ant
cannot be adjusted.
• Idle soeed setting - With throttle centre
lever in slow position, engine should idl_
at 1200 RPM. If engine idles too slow el
fast, turn idle speed adjusting screw in o=
out until correct idle is attained.
• Idle fuel needle settina - With throttle
control lever in slow position, turn idle
fuel adjusting needle in (clockwise) until
engine speed decreases and then turn
out (counterclockwise) approximately 3/
4 turn to obtain the best low speed per-
formance.
• Recheck idle speed. Readjust if neces-
sary.
ACCELERATION TEST -
• Move throttle control lever from slow to
fast position. If engine hesitates or dies,
turn idle fuel adjusting needle out (coun-
terclockwise) 118 tum. 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 eninge
governor, which is factory set for proper
engine speed. Overspeeding the engine
above the factory high speed settng can be
dangerous. If you think the engine-gov-
erned high speed needs adjusting, contact
your nearest authorized service center/
department, which has proper equipment
and experience to make any necessary
adjustments.
