"I never made it to full throttle. It would drop to about 3.5 when I would put the throttle about half way down- rpm was around 2800 or 3000. If I rolled on the throttle, it would pull hard, but if I stepped on it, it would hesitate/miss for a while and eventually smooth out and pull hard. This was the same with the standard spring in the secondary or the small yellow spring. "
the hesitation of WOT is accell pump related. Try the green cam and a bigger squirter. The secondary spring will be of no effect for this problem. It also sounds like the PV isn't opening and adding the fuel enrichment for WOT if you have a "it would hesitate/miss for a while and eventually smooth out and pull hard" the accell pump will only cover up a small lean condition. Sometimes going up one jet size will take care of this kind of lean miss, when you can't get it all with the accell pump. Your eyes shouldn't be burning however.
