If you want to try to learn the physics of it then I'd reccommend Larew's 'Carburetor & Carburetion' (something like that), its a college level engineering book that takes you thru the physics on how to calculate and design a carburetor, what all those holes do and why they are where they are. It is a tough read, I think its meant to be used in the classroom where the teacher can fill in some of the gaps in the calculations. It is math heavy.
If I remember right, at the end, the 'final exam' is where you design a 1bbl carb for a stationary 4cyl, 150ci engine that makes 100hp at 2500rpm and the carb has a 3/4" throttle blade, show all calculations (incl air bleeds, velocity, volume etc); the 2nd question is the same carburetor with an 11/16ths throttle blade.
