Problem with Holley 4 bbl

Can we get a list or model number? How much adjustability does the carburetor have? Air bleeds? Fuel restrictors? What exactly are we talking about in a carburetor here?
Its a 3310-2 VS 750 CFM. Air bleeds are not adjustable. Only things you can readily adjust are idle fuel mixture via the screws, main fuel mixture via standard jets and PV, secondary main metering via a plate, primary and secondary throttle blade positions, float level, and VS opening rate via a diaphragm spring.
