Too Slow/Q-Jet question

All were set up the same metering rods and hangers. All were known builders.

I don't really have the funds to buy a name brand, brand new Q-Jet, but do you know of anyone in the NC/SC area that can at least go through one and tell me what I have? From what I understand and the previous owner of the car, my Q-jet was gone through, rebuilt, and ran well on another combo, but truthfully I do not know enough about it to say if that's true or if it's right for my combination. If there is even tenth to be found in the tune-up, that'd be all I need. I'm already under the index in good air, but as soon as I get to marginal air, I'm in trouble.
