Starting with 1973 USA models, the anti-deiseling valve was added. This is an idle-circuit cutoff solenoid. As soon as the key is turned off, the engine dies.

Anti-Diesel solenoid valve (some 1973 and newer carbs)

Wiring

• Yellow wire - fuel cut solenoid To general IG circuit (hot when key is Run or Start)

Troubleshooting

• Turn the key to IGN. Then unplug the connector at the valve (under the engine). Does the Anti-disel valve have 12V at the wiring connector?

  

  • test to see if you have power ay the plug that the solenoid connects to

Yes: Have someone turn the ignition on & off while you listen carefully to hear the 'click' as it is turned on.

• No click? Remove the solenoid from the carb and take out the 'pin' in the middle & refit the main body of the solenoid. Start engine to see if all is well. If this fixes it, then repair wiring or replace solenoid with a working one.

No: Check your fuses...trace the wires and see why it's not getting power
