Carb kit or replace carb?
1976 with 48k miles. Stalled out yesterday and had to stomp on it a few times to get it running. Feels like it is choking out. Since it has sat for a long time and putting a can of carb cleaner through it with out much luck, is it easier to rebuild or buy a reconditioned carb to go on it? It chokes out fairly easily with any hard acceleration.

I assume it is the original Quadrajet? It sounds like your accelerator pump cup has gone bad.
Get a metal bucket, a gallon of lacquer thinner, chemical resistant gloves, a non-plastic brush and if you don't have an air compressor, get a rubber irrigation bulb (like what they use to suck snot from a baby's nose).
Take the carb apart, (don't remove the throttle plates) making notes on how everything hooked up. Seat and record the number of turns on all adjustment screws.
Soak all non-plastic parts in the thinner and use the brush to clean. Blow compressed air or thinner (with the bulb) through all passages. (wear safety glasses).
Buy a carb kit and put everything back together using the new parts in the kit. Set all adjustments as they were in your notes and re-install the carb.
That should take care of it and you have the satisfaction of doing it yourself.
God bless, Sensei
P.S. This whole process will cost considerably less than a cheap junk aftermarket carb, and you will still have a Quadrajet (which is a good thing)

Most complete kits available:
http://www.cliffshighperformance.com/parts.html#
The kit is based on your carb, not some generic kit.

Yes, but are you going to do with a gallon of lacquer thinner afterwards? Just buy a re-built unit. Let the pros handle the environmental considerations. Despite what you read hear there are very competent re-builders. NAPA Canada has one of the best.

And its as if a repair shop is a guarantee that the process is environmentally friendly. Rebuilding your own unit is environmentally sound because it isn't going into the dumpster.
There are many brands of solvents out now that are safe for the planet, how about you do the job yourself with those so tree huggers can sleep better.
