MotorCraft question
i recently rebuilt and installed a motorcraft 2150 carb on my 86 cj7 with a 258. ofcourse it runs to rich when your on the throttle. the rpm jump all over and has no power to do any kind of hill. what size jets are you guys running on your mc2100s? and do you think this would fix the problem?

Are your vacuum lines all good?

vacuum lines should all be in the proper places. i dont think that would make it run so rich when im on the throttle any way.

Vacuum ports or lines open would make it run incorrectly and so then when you set up the idle it would be off from the start.

Is the float set up correctly? Both wet and dry?

im sorry im a novice with carbs so this might sound dumb. theres a wet and dry setting for carb?
