carb ID and adjustment help
I could use some help identifying and adjusting my carb. I've worked with Jeep carbs before, but I'm not familiar with the Rochesters. Does anyone have information on identifying the specific model carb I might have (such as pictures or where the model numbers are on the rochester 4bbl).
I'm also looking for help adjusting the carb to fix several issues I have. Right now I have a lot of plugged lines, open lines, no fast idle that I can find. The carb runs ok warm, but not very well cold and the manual choke I just installed has no effect on how it runs cold, so I assume I have several carb leaks and the idle and mixture settings need to be adjusted to optimize vacuum and fuel ratio. Any help, tech articles, etc would be greatly appreciated. Take care JohnWayneJeep

Re: carb ID and adjustment help
Carb ID should be on the drivers side. Either an aluminum tag or a number stamped near the back.
Can you post a pic of what you got?
