I can read something 1,000 times and not know what I have read. I can do it a few times, but also have to think real hard to remember what I did. I have to look at something very hard to remember what went where. Looking at pictures, or someone explaining it simply helps me get the job done. I'm not rich. I can't afford $300 for someone to rebuild. I may be going blind, and getting hard to hear, and arthritis is in both of my thumbs, but I am trying as hard as I can to build it myself. That is with the help of people online.
The adjustment screws must be off some.. If I start it up, and let it get warm. If I pull off the vacuum line. Can I then adjust those screws in the front??

Al,
With all due respect your post describing your ailments explains a lot about your problem. In several of your posts people have given you suggestions that seem to go by without any consideration (may not be the case, but it seems that way). If (and this is a BIG IF) your carburetor is "gunked up" it is likely not just sediment in the bowls that can be sucked out and make everything OK - the "gunk" is going to be deposits and plugging in internal passages that can only be removed by complete disassembly, thorough cleaning, and careful reassembly, which I would say you should not tackle alone based on what you've told us today. I still am not fully convinced that your problem is in the carburetor. If you're getting a strong shot of fuel from the accelerator pump then it makes sense that if you "really pump it" then you're going to have to hold the pedal down to clear that fuel - you're flooding the engine, and you may well have fouled the plugs if you've done this many times. It seems to me that the things you've described could be ignition related, but trying to pinpoint it in this venue is tough. This might be solved by simply taking the car out and "blowing the cobbs out of it" with some highway miles, and a few hard pulls to clear things out at temperature.

I believe you mentioned being part of a "car group" or having friends in the car hobby in your area. I think it is time for you to call on one or two of them to come help you assess exactly where your problem lies, and then tackle it in a logical, step by step process using solid troubleshooting. Best of luck to you - sincerely hope you get it running right. It's a nice looking car.

Ok. Thanks. I will give it a try. Al

Sitting for a couple of months could be some of your problem. Gas turns to crap VERY quickly these days and gums stuff up. When I was in the marine business it was a very common problem for someone to lay up their boat and then when they came back to use it a couple or 3 months later it wouldn't run or run right. A huge chunk of our business came from cleaning carbs and injectors.

You might try one of the additives first. I think if that is your problem it will take a disassembly and soak to really make it right, but what have you got to lose except $ 5 or so dollars for some additve. Lucas makes some good stuff and so does SeaFoam, to name a couple. A while back I had to take my daily driver in to the dealer to have some injectors cleaned and replaced and while they were at it they put in some GM injector cleaner to clean up the rest of the system. So I guess even GM techs have some confidence in cleaners.

Thanks. I'll buy some Seafoam..

Ditto what Roger just said!
Take it out and give it a kick in the A** with a couple hard pulls.
Blow the crap outta it.

I had the exact same problem with my 600 elderbrock carb. Found out that my check valve was bad. Had some gunk in the chevk valve and after ckeaning it out, never had to pump the pedal more than once. Not saying this is your problem but could be.

Guess I will have to pull the top off then.. looked at the pictures at the Edelbrock site, and there sure are alot of parts in there. Now would I be able to do this with the carb still on the intake, or do I have to take it off??

oh, and I can't just take it out on the road and fire it up. There is no glass in it, and no plates on it. The Police frown on this.. Can't get plates untill I get insurance. Can't get insurance untill I am 80% done. I am only about 65% done..
