TO ADJUST
CARBURETOR
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.
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
idle mixture
valve in
(clockwise)
decreases
the supply of fuel to
the engine giving a leaner fuel!air
mix-
ture.
Turning the idle mixture
valve out
(counterclockwise)
increases
the supply
of fuel to the engine giving a richer fuel!air
mixture.

IMPORTANT:
Damage to the needle
valve and the seat in carburetor
may result
if screw is turned
in too tight.
