I was in the same boat you are in, I wanted to resolve as many of these issues ahead of time to get the car driveable and to minimize chassis dyno time/expense. But in my opinion, you cannot solve these subtle carb issues until the timing is right, including and especially the curve.

Not trying to be argumentative, but if it were me, I'd first lock the timing out of the distributor at idle. Then I'd baseline that carb to 1.75 turns out on all 4 corners, confirm the transition slots are correct and use the Idle-Eze to get a level idle. Then I'd unlock the advance and start trying to experiment with initial and advance settings. Once you get that done, then you can finish with the carb tuning. But I think Jerry Clayton is right, you are likely seeing issues caused by timing not matching the carburetion, not the other way around.

Good luck.
