FUEL SYSTEM AND GOVERNOR
Shutdown Control Function
The engine shutdown control device is a solenoid
and plunger mounted on the carburetor which
prevents the engine from "running on" after the
ignition is turned off. See Figure 4-11. When the
switch is in the start position, battery current thru
the solenoid holds the plunger and continues to
hold it while the engine is running. When the
switch is moved to the stop position the solenoid
de-energizes and drops the plunger into a porting
in the carburetor to stop all flow of fuel.
The engine shutdown control has two lead wires
on it- a ground lead from the top of the shutdown
solenoid and a power lead from the bottom of the
solenoid. The power lead is wired into the (+)side of
the ignition coil.
Shutdown Control Inspection
1. Make sure the solenoid has a secure electrical
connection and good contact with the retaining
bracket (ground).
2. Check for stuck plunger. Replace if damaged.
3. Check for defective solenoid with an ohmmeter
or multimeter. Solenoid resistance is approxi-
mately 20 ohms.

Shutdown Control Test
Refer to Figure 4-11 lor identification of parts.
1. Remove shutdown control (solenoid and plung-
er) from carburetor body by loosening the main
fuel adjusting screw so the bracket holding the
control can be shifted. Do not disconnect the
lead wires.
2. Pull the shutdown control out of the carburetor.
3. Hold the plunger approximately 1/ 4" away
from the solenoid. Turn the ignition switch to
"ON" and release the plunger.
If the plunger is drawn into the solenoid, the
shutdown control is functioning properly.
If the plunger is not drawn into the solenoid, the
solenoid is faulty and must be replaced.
As a temporary fix, until a replacement solenoid
can be obtained, the plunger can be removed from
the shutdown control and the solenoid reinstalled
minus the plunger.*
After replacing solenoid, reset main fuel adjusting
screw according to procedures under "To Adjust
Carburetor''.
*The removal of the plunger will not affect normal car-
buretor function; however, to
prevent unfiltered air from
entering the carburetor, the defective solenoid must be
reinstalled over shutdown control vent hole, after the
plunger has been removed.
