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 timiter 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.
PRELIMINARY
SETTING
-
1, Air cleaner
assembly
must be assem*
bled to the carburetor
when making
carburetor
adjustments.
2.

adjusted
properly
(see above).
FINAL SETTING
-
1. Start engine
and allow to warm for five
minutes.
Make final adjustments
with

2,
Move throttle
control
lever to slow posi-
tion. With finger, rotate and hold throttle
lever

to attain 1750 RPM.
3. While still holding
throttle
lever against
idle speed
screw, turn idfe mixture
valve full travel clockwise
then coun-
terclockwise
until engine
runs rough.
Turn valve to a point midway
between
those two positions,
Release
throttle
lever.
ACCELERATION
TEST -
4.
Move throttle
control
lever from slow
to fast position.
If engine
hesitates
or
dies, turn idte mixture
valve out (coun-
terclockwise)
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.
Overspeed-
ing the engine above
the factory
high
speed
setting
can be dangerous.
If you
think the engine-governed
high speed
needs adjusting,
contact
a Sears or other
qualified
