My Dad just picked up a 47 cj2a. It is completely stock and in great shape. It runs good except for the first tiny bit of throttle above idle. if you try to roll on the throttle smoothly it will stumble and stall. If you blip it and get the revs up a little bit then it will run fine. If runs smooth and strong at all other engine speeds. This makes it annoying in town and off road. Any ideas? I have not taken the carb apart yet. the jeep has been driven regularly and been well taken care of. I do not know if the previous owner rebuilt the carb or messed with it at all. Any help would be appreciated. Thanks!
