new carb hesitating a bit

I just put a brand new out of the box Holley 650 on my buddies '32 Ford... got it running fine but not "perfect". I thought it was pig fat cause it felt a bit lazy in the bottom end... and it had a bog if you jumped in it.

Some of this stuff takes a pro and takes equipment (tail pipe sniffer etc) to sort out even if you're real familiar with carbs and timing etc. You could spend days trying to sort out all the advice and tips you're going to get in forums like this.
