I had no luck with the timing change so its back to where it was. So I hooked up the timing light. I tune the carb to 750 in N w/hi-beams on and adjusted the A/F ratio. So I take the car for a test drive and I find out after getting back and rechecking it that it is now idling at 680 in N w/hi-beams on. I readjust and cycle through the gears and it idles a 817 when the car never moved and I went from P to 1st and stopped in N. I readjust and The idle drops to 728 and I go to where the idle Speed screw was when it was 817 and it goes to 755. I let it idle and it goes from 755 to 746 to 756 to 768 and it bounces from 738 to 770 and never returns to 750. I think it may be time for a carb rebuild.

Go ahead and save that weird car, the sedan, the 6 cylinder, the C-Body. If you want a big block musclecar and that's all you care about, your missing the point.

Did you check to see if the throttle shaft that opens and closes the butterflys is lubricated and rotating freely?

Yes. It is
