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 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,
proceed
as follows:
In general,
turning
idle
mixture
valve
in
(clockwise)
decreases
the supply
of fuel to
the engine
giving
a leaner
fuel/air
mixture.
Turning
the idle mixture
valve
out
(counter-
clockwise)
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.
