Tuning a Proform/Holley carb, what parts and tools?

I did. It ran good at first, then total crap.
I took it to my normal spot, as I hit third at about 90mph I could feel it falling flat.
If I get on it from a dead stop and let off, it dies.
If I get on it starting from 20 and let off, it dies.
Even died on ne twice in a grocery store parking lot at idle, and must be flooding because it would not fire back up without holding the pedal down.
While my amatuer tuning attempts might be contributing, I think I may have a fuel issue and or ignition issue or both. I just replaced plugs and wires. Starting to suspect the coil or voltage regulator, and or fuel pump.
I have had issues with three different carbs now.
I worked all night and I'm so tired and pissed. I might pull the plugs, but getting into the carb will have to wait.
