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

Didn't make it to the show, cranked fuel pressure back to 4psi on the guage. Went and bought a new air filter, and the carb soaked it in gas the first mile.
Had to take it off just to get home.
Really starting to get pissed with this carb!!!
Trash in the needle and seat?
Floats too high? (just above middle, but lower tha they were out of the box)
Faulty psi guage?
Filled the tank with $25 worth of fresh gas.
Lines don't feel hot, would say maybe the carb is getting hot if it hadn't run fine before...
I probably jacked something up, but too frustrated to mess with it anymore today!
Gonna pull the carb off tomorrow and disassemble it.
Don't think iI blew the PV because the mixture screws are still responsive, but I wiil swap a new one in tomorrow, anyway, card says it has a 6.5 in it. I only get about 9" of vacuum with this cam, which PV should I try? Could the 6.5 be part of my problem?
Any other tips on what to look for that hasn't been mentioned?
