Check the Manufacturer’s Manual to see if the RPM adjustment
is necessary.

See below for RPM adjustment.
Make sure the throttle solenoid linkage is adjusted properly. With the clutch disengaged,
the throttle linkage should rest against the idle adjustment screw. With the clutch
engaged, the linkage should rest against the high-end adjustment screw and leave 0” to
1/32” of play in the linkage.
CAUTION!
Failure to properly adjust the throttle solenoid linkage may
cause damage to the solenoid.

Disengage the clutch and loosen the solenoid mounting bolts to adjust the throttle sole-
noid linkage.
2.
Adjust the solenoid as far to the right as possible and retighten the mounting bolts.
3.
Engage the clutch and recheck the amount of play in the linkage.
If there is more that 1/32” of play in the linkage with the clutch engaged, disengage the
clutch and turn the linkage turnbuckle.
4.
Repeat adjustments to achieve 0”-1/32” of play in the linkage with the clutch engaged.
