Try bumping the the timing 4 degrees and run the the vacuum advance off manifold. That might be enough to fix the hot running issue. The trans may need some gaskets and maybe some governor mods. The modulator is hooked up to vacuum?

I think that trans is probably junk remember what I went threw to get it? I'm probably going to finds another one who knows what that guy did to that thing. I doubt I'll be able to enjoy the car this season anyway. Still trying tho
Glad to hear you got it running!! That is awesome, sucks about your trans though. Keep at it! Youre doing good so far! and better than some! haha
It may need the APT adjusted richer. Those late 70's carbs are lean, your builder might have calibrated it slightly lean. This is assuming a proper pump shot.
Inside of the carb under the cup plug, the stand that limits primary metering rod movement. I notched mine and put a thread in plug in place of the cup plug for easy access.
Keep track of where the APT is as it is now so you can return it to it's original position later. Unless you want to buy an AFR gauge.
