Keep pluggin away at it Gerig. You will eventually figure it out and when you do you will be a better mechanic. This is how you learn things. I know it is sometimes frustrating but replacing it is the expensive and easy way out. I can't tell you how many times a customer brings in his car with a trunk full of replaced parts only to find that he still has a problem and can't figure out why he is broke! Its amazing they have a short in the wiring and by the time he gets the car to my shop it has a new alternator, new battery, New cables, new starter etc. And theres nothing wrong with the old parts! Hell we put our shop car together from mostly customer discarded parts! Its hillarious! I would suggest taking the carb completely apart and soak everything in carboline for a few hours and and put it back together with a new kit and all metering rods and jets that were original to that carb. 9 out of 10 times a piece of dukey is blocking an orifice and reaking havoc on your engine and mind. This is probably why everything that you have tried that should have worked didn't.....Goodluck.

I have just went through many troubles with my edelbrock and im gonna give my 2 cents, if you have the manual,( which after reading 40 times still never helped me) then go to the part about setting floats, it very well could be a metering problem but set your floats, it describes how to do that, make sure you set the floats BOTH WAYS, not just upside down, with the top sitting the right way there should be appox. 15/16s to 1 inch between the top(with gasket on it) and the top of the end of the float, make sure you bend the tabs at the right spots also. I could be wrong but it couldnt hurt to take the screws out and check this. GOOD LUCK, keep us updated. Also check your plugs, and be sure to check your fuel pressure and fuel filter, tons of "carb probs" are actually other stuff. good luck again.

71 Nova makes an excellent point. Many times people replace their carb only to find that the problem lies somewhere else.....

Just a idea you said you have no change when you try to set your air mixture. Try spraying some carb clean around the base
of the carb to makesure you don't have a small vac leak. I had a
simular prob with a q-jet once. It turnerd out to be a air gape
about as thick as a peace of paper under my mixture skrews.

I'll try that, I didn't even think of a vac. leak. Tommorow I'm going to check out all of the other systems to make sure they are all working right. I took one of the plugs out and it is really sooty so even if the stuttering is from another system I'm still gonna hafta tune it right.

Sounds like maybe you're not really on the idle circuit at idle. I'ld pull the carb and look carefully at the butterflies. The primary should be just about ready to expose the tiny transfer slot in the bore. Also make sure the secondaries are shut. I don't know about yours, but there's usually a stop screw in the baseplate that can hold the secondaries open. This is usually adjusted for big cams so you don't have to open the primary so far as to get into the transfer circuit. The transfer circuit handles the transition from idle to the main circuit, and if your on it the idle mixture adjust screws won't have much effect. Hope this makes sense.
