Have you ohm'ed out the plug wires? Also do a wiggle check for side to side slop on the dizzy shaft. The Pump may be on the weak side as far as internal regulation. I will bring by a vaccum guage when I get home and you can test to see how the tuning it with that differs from the timing light.
Are you using new base plate gasket every time🤔? I still say there's a vacuum leak and the timing is off. Does anyone have a better carburetor that you can use?
No one has a carburetor I can use. This one is brand new. I have checked for vacuum leaks until I'm blue in the face. If I pull the dipstick from the oil catch can or a vacuum line, the idle goes crazy. Nothing else makes a difference. I agree about the timing, but I don't know why. It's a new harmonic balancer, and it points to TDC. But anything below 18° and it sputters and backfires. I've run up to 22° and it runs better. It doesn't detonate at 22°, but I turned it down anyway and haven't been willing to risk trying more. I'm starting to think I installed the new Cloyes adjustable timing chain to -4° retarded or something. 😕 It's one of the chains with the triamgle and square symbols instead of just saying "TDC/+4/-4." I may have rushed it and not put it straight up. I don't know.
5th gear pulls smoothly now. It may not be a power gear, but I shouldn't have to downshift to go from 65-75. Before, it was shaking badly. Now it accelerates nicely. I checked the vacuum recently. I think I had 15-16". They are adjustable rockers. I've tried adjusting them and haven't seen any change.

Fifth gear is for cruising not pulling🤦♀️. Find out how much vacuum you have🤨. Also I presume that these are non adjustable rockers?
