Maintenance, repair, or replacement of the
emission control devices and systems,
which are being done at the customers
expense, may be performed by any non-
read engine repair establishment or
individual. Warranty repairs must be
performed by an authorized engine
manufacturer's service outlet.
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 countemlockwise 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 withthe
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.
