Normally I would advise to learn how to rebuild one. But I can sense the OP is not into it and the E-Qjets are pretty tough even for a pro. Of course if you could score a swap meet or EBAY carb cheaply then you could just clean it up and use it. THEN get the original done right.
I oddly enough have avoided carb'd motors my entire life and gone LT4 and LS3 swaps, but I bought my father a low original mile 1986 305 El Camino and myself a completely redone 1987 307 Cutlass Supreme, so I want to slowly read and learn all aspects before I ever tear into my own personal vehicle or my fathers. I work on the Cardiac unit at my hospital, so I can't afford to cut my hands up and go into work... risking acquiring or spreading anything to my patients. But I'm fairly certain, if I continue to read diagrams and more info on these carbs, I'll eventually understand them.
The other issue is my father is an impatient child and already took the carb off, ready to rock and roll and I left South Florida and won't be back for a few months, so I'm trying to assist him from afar.
