TO

CARBURETOR
NOTE:
The
carburetor
on this
engine
is
low
emissiom
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
offuel
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.
