TO ADJUST CARBURETOR
The carburetor
has a high speed fixed jet
and has been preset at the factory and
adjustment
should not be necessary.
However, minor adjustments
may be
required to compensate
for differences
in
fuel, temperature,
altitude or load. If the
carburetor
does need adjustment,
proceed
as follows.
IDLE RPM ADJUSTMENT
• To adjust idle RPM, rotate throttle
linkage counterclockwise
and hold
against stop while adjusting idle speed
adjusting screw to obtain 1750 RPM.
Release throttle linkage.
ACCELERATION
TEST
• Move throttle control lever from "SLOW"
to "FAST" position.
If engine hesitates
or dies, turn idle needle valve out
(counterclockwise)
1/8 turn.
Repeat test
and continue to adjust, if necessary,
until engine accelerates
smoothly.
High speed stop is factory adjusted.
Do
not adjust or damage may result.
IMPORTANT:
Never tamper with the
engine governor, which is factory set for
proper engine speed,
overspeeding
the
engine above the factory high speed
setting can be dangerous.
If you think the
engine-governed
high speed needs
adjusting, contact your nearest authorized
service center/department,
which has the
proper equipment
and experience
to make
any necessary adjustments.
