My '71 has had an ongoing problem with engine dieseling. In the past I've set the engine idle very low and turned the car off in gear. This works most of the time but I still see some dieseling. I was researching dieseling and saw some discussion about factory stop idle solenoids to help this problem. I found the Edelbrock solenoid 8059 that seems like the same thing as the factory stop idle, but all the descriptions say its for use with factory AC to bump the idle under load. Is anyone running this solenoid to help with dieseling? I'm running an Edelbrock 1806 650 AVS Thunder carb with electric choke. Sounds fairly easy to set up, but the part is a bit pricey.
