Wow I didn't expect the responses I got on here but this is what I found in my searching for the Idle stop solenoid for the Varajet. The closest one I found that matches the pic that
@justhorns posted was a Borg Warner ECS48 idle solenoid and GM 17057277. There is also a AC Delco part number 8137238 that is similar but the wire connector pops off the side like the first two listing in
@AuroraGirl post #18. Also I noticed that Part store suggest Standard Motors Idle Stop Solenoid ES9 as a possible replacement which is similar to the 214-2138 that is in
@AuroraGirl post #18 and the one that
@Bextreme04 said is for the quadrajet. With the Standard Motors ES9 at least that one is still manufacturer. So which still leave me in a dilemma still. This wouldn't be a problem if the original carb was left on the truck but they took the original Varajet off the truck, did a DIY propane conversion on it 40+ years ago, put a monojet with 2 difference adoptor plates on the 2 barrel intake manifold that lifted the monojet carb up like 2 and half inches, now that I'm converting it back to run on gas the monojet wasn't getting full throttle because it's sitting to high up.
