These pictures are great references. Studying them can pay dividends!

You may still need to work a bit to figure out some of the acronyms because of minor variation in name or order of words in the acronym. Here is a cheat sheet:

IFR: idle feed restrictions, sometimes called the idle jet. #4 on the second picture, although some metering blocks have them at the top and others at the bottom of the idle down well.
PVCR: power valve channel restriction. #17 on the second picture.
PV/HFPV: power valve/high flow power valve which is a different style PV. I used PVC but that was a typo. #16 on second picture.
MS: mixture screws. #13 in third picture.
IAB: Idle air bleed. This is in the top of the barrels, and controls the amount of air admitted to the idle well which is fed with fuel by the IFR. This circuit controls the fuel/air mix sent to the idle circuit (controlled by the MS) and the transfer circuit.
HSAB: High speed air bleed. This is in the top of the barrels, and controls the amount of air admitted to the main well which is fed with fuel by the main jets and the PV via the PVCR. The HS part is to distinguish it from the idle system, and because it has the most effect at high air flows. The HSAB are closest to the squirter on Holley-like carbs.

QF/QFT is for QuickFuelTechnologies which is a carb vendor.
