tion. Slowly move lever from choke to
fast position.
• Check to see if hole in throttle lever and
hole in speed control bracket are

• If holes are not aligned, loosen cable
clamp screw and align the holes by in-
serting a pencil or a 1/4" drill bit through
both holes.
• Pull throttle cable up to remove slack

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 adjusting needles
in (clockwise) decreases
the supply of
fuel to the engine giving a leaner fuel/air
mixture. Turning the adjusting needles 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
needle is turned in too tight.
NOTE:
The carburetor on this engine is
low emission. It is equipped with an idle
fuel adjusting
needle with a limiter
cap,
which allows some adjustment
within the
limits allowed by the cap. Do not attempt
to remove the limiter cap. The limiter cap
cannot be removed without breaking the
adjusting needle.
• Be sure you have a clean air filter and
the throttle control cable is adjusted
properly (see above).
•
• Start engine and allow to warm for five
minutes.
Make adjustments
with engine
running
and shift/motion
control lever in
neutral (N) position.
Idle speed setting - With throttle control
lever in slow
position, engine should
idle at 1750 RPM. If engine idles too
slow or fast, turn idle speed adjusting
screw in or out until correct idle is at-
tained.
• Idle fuel needle f_e_tin9 - 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 mid-
way between those two positions.
• 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
(counterclockwise)
1/8 turn. Repeat test
and continue to adjust, if necessary,
un-
til engine 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-
ing, contact your nearest
AUTHORIZED
service
center/department,
which has
proper
equipment
and experience
to
make any necessary
adjustments.
