TO ADJUST
THROTTLE
CONTROL
CABLE
The throttle 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
follows:
• With engine not running, move throttle
control lever from slow to choke
position. 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. Re-
move alignment pencil or drill bit.
TO ADJUST
CARBURETOR
The carburetor has been preset at the
factory
and adjustment should not be
necessary.
However, minor adjustment
may be required to compensate
for
differences
in fuel, temperature,
altitude or
load. If the carburetor does need adjust-
ment, 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
(counterclockwise)
increases the supply
of fuel to the engine giving a richer fueVair
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
attained.
• Idle fue! 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.
