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:
1. With engine not running, move throttle
control lever from slow to choke posi­
tion. Slowly move lever from choke to
fast position.
2. Check to see if hole in throttle lever
and hole in speed control bracket are
aligned.
3. 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.
4. 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 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
(counterclockwise) increases the supply
of fuel to the engine giving a richer fuel/air
mixture.
IMPORTANT: Damage to the needles and
seats In carburetor may result If 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.
