Fuel Shut-Off
Carburetor incorporates an idling speed shut-off (fuel shut-off) valve. Valve is activated by a time delay switch, located in feed line from ignition switch. When ignition switch is turned off, time delay switch interrupts current to idling speed shut-off valve. Valve closes stopping fuel from entering carburetor. After a period of 6-8 seconds, time delay switch reopens idling speed shut-off valve.
