ENGINE
TO ADJUST THROTTLE CONTROL
CABLE
The throttle 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 throttle
control lever from slow to choke posi-
tion. Slowly move lever from choke to
fast position.
• Check to see if hole in throttle lever and
hole in speed control bracket are
aligned.
• If holes are not aligned, loosen cable
clamp screw and align the holes by
inserting a pencil or a 1/4" drill bit
through both holes.
• Pull throttle cable up to remove slack
and tighten cable clamp screw. Remove
alignment pencil or drill bit.
TO ADJUST CARBURETOR
]he carburetor has been preset at the fac-
;ory and adjustment should not be neces-
sary. However, minor adjustment may be
"equired to compensate for differences in
uel, temperature, altitude or load. If the
"arburetor does need adjustment, proceed
is follows:
n general, turning the adjusting needles in
clockwise) decreases the supply of fuel to
le engine giving a leaner fuel/air mixture.
urning the adjusting needles out
:ounterclockwise) increases the supply of
Jel to the engine giving a richer fuel/air
_ixture.
IMPORTANT: Damage to the needles and
the seats in carburetor may result if nee-
dle 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 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 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,
until engine accelerates smoothly.
High speed stop is factory adjusted. Do
not adjust - damage may result.
