TO ADJUST CHOKE CONTROL
The choke control has been preset at the
factory and adjustment should not be
necessary. Check adjustment as de-
scribed below before loosening cable. If
adjustment is necessary, proceed as fol-
lows:
• With engine not running, move choke
control (located on dash panel) to full
choke position.
• Remove air cleaner cover, filter and
cartridge plate to expose carburetor
choke (see AIR FILTER" in the Mainte-
nance 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 se-
curely.
• Reassemble air cleaner.

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
to the engine giving a leaner fuel/air mix-
ture. Turningthe m_xture screw out
(counterclockwise) 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. 26
PRELIMINARY SEI-FING -
• 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) 1-1/4
to 1-1/2 turns.
FINAL SE1-FING -
• 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-
gine-governed high speed needs adjust-
=ng, contactyour nearest authorized ser-
vice center/department, which has proper
equipment and experience to make any
necessary adjustments.
