1984 k5 Blazer (Rochester Quadrajet Carb)

What is your question?

Replaced 350 motor w/350 gm goodwrench motor. Carburetor sat for 6 mos. Truck starts and idles fine, it gets to a certain rpm and falls on its face and you have to back off the gas, it also is running very rich, so bad that it burns your eyesand your clothes smell like gas/exhaust. Fuel pump press. checks out, no vacuum leaks all electrical has been checked out and is fine. Does this sound like the carb needs to be rebuilt?
