TO ADJUST CARBURETOR
The carburetor has a high speed jet and
has been preset at the factory and adjust-
ment should not be necessary, However,
minor adjustments may be required to
compensate for differences in fuel, temper-
ature, altitude or load. If the carburetor
does need adjustment, proceed as follows.
o Move throttle control lever from "SLOW"
to "FAST" position, tf engine hesitates
or dies, turn needle valve out (counter-
clockwise) 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 en-
gine governor, which is factory set for
proper engine speed° overspeeding the
engine above the factory high speed set-
ting can be dangerous. If you think the
engine-governed high speed needs adjust-
ing, contact your nearest authorized ser-
vice center/department, which has the
proper equipment and experience to make
any necessary adjustments.
