Adjustment screw is not used to ad-
just engine speed when automatic
idle option is installed. However, it
must be at least 1/8 in (3 mm) away
from the throttle arm when engine is
running at idle rpm.
Unhook rubber boot from the sole-
noid housing but leave connected to
plunger.
Loosen lock nut. Place Engine Con-
trol Switch in Auto position.
Turn throttle rod and plunger until
engine runs at idle speed. Tighten
lock nut.
Hook rubber boot back onto sole-
noid housing.
Be sure solenoid plunger pulls
all the way in (“bottoms”) when
energized.
Weld/Power Speed Adjustment
Weld/power speed adjustment
must be done by the engine
