Carburetor Tuning Continued

I received the new distributor springs, Petronix FlameThrower Coil, and MSD Street Fire spark plug wires in the mail today. The springs are rated to deliver full mechanical advance by 2,400-2,800 RPM. I was concerned that would be too quick so I used one and one of the stock springs.

I drove the car around tonight with only the new spring installed. This seemed to help low RPM performance some but did not fix the hesitation. I posted on a few Mustang forums to get some additional help with the problem. The only response so far requests I try new pump cams.
