Carb issues

I have a 68 cj5 - I believe with a 225 v6. I purchased it 20 years ago (it has sat covered most of the time). I am just now getting around to fixing it up. I rebuilt the carb. The carb is not the original - it is a Holley and according to the numbers - it was made for a 360 size engine. It runs at high rpm, but dies when trying to idle ( unless the chock is almost fully engaged). Even after rebuilding, cleaning, blowing out and new parts - it does the same thing. I even turned in and our both air/fuel screws - all the way in and taking them all the way out - the rpm's never really changed. Again - it was running at about 1500 rpm. Any help with this carb would be appreciated or do I need a new carb? Any recommendations?
Thanks

First, please identify the carb. Holly manufactured many carbs of various design's, identifying what you have will greatly help us.
That aside, insure you don't have any vacuum leaks. Check around the base of the carb and the PCV valve hose.

The carb is a Holley R 8699. I have not noticed any leaks. All vacuum ports have been blocked (rubber boots - all new) except for the vacuum advance ( I can pull this off and the engine speed will change slightly). The PVC hose comes out of the top of the carb - it is a new hose. Can I go to the junk yard and fined a Buick v6 carb that will bolt up? I assume based on what I have said - full chock to run - that I have an air leak somewhere? Since all ports have been blocked - the only other possibility would be the base gasket - I will pull the carb and use a gasket sealer and let you know. Thanks

I believe that is a 2210. These are notorious for being somewhat cranky.
Your stock carb would be a Rochester2GC


These are excellent carbs, and though somewhat restricted CFM wise, offer very good economy and outstanding offroad performance.
