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?
