I also hear something about a nutter. What exactly is that and do I need it?

First off I want to take up for the Weber! A Weber is a very good carburetor! But to run rite they do require some tuning. Where a motorcraft is a more forgiving carb, but that is mostly due to the larger Venturi s. if you have the knoll age and tools a weber should and in my opinion will out perform a motorcraft. Now don't get me wrong i like motorcraft, I have owned a lot of Fords! But the Webers get sold short to many times because they are not understood! My weber runs perfect on my 4.7 stroker, gets 23+ mpg! But did require extensive tuning! Ok enough on webers. A nutter job is to bypass the factory computer, yes in my opinion your jeep will run much better with it done! There is plenty of info on how to do it, and several ways it can be done. Personally I would go with a MSD or Accel system

NOTE!
If you have a Carter with electric choke you can re-use it on the MC but you HAVE TO REVERSE THE SPRING.. It either goes clockwise on the Carter and CCW on the MC or the other way around but whichever, if you don't do it the best you will get is no choke, the worst is the choke closing as the engine heats up.

If you go to the stickies at the top of the page, then to the YJ FAQ, then to the engine/ carb section, there are three good write ups on the nutter bypass. I found the one called picture guide to the nutter bypass particularly helpful.

When you replace the carter carb with either the weber or motorcraft, you take the computer out of the loop in controlling the carburetor.

When you do the nutter bypass, you take the computer out of the loop in controlling the didtributor/ignition.
