Nutter Bypass

Has anyone ever done this bypass? If so, did it make much of a difference? I have a friend of mine that did this to his Jeep and dramatically improved the performance of his engine. I was considering doing this to my 83' CJ-7 with a Weber carborator.

Made a big difference when I did it after installing the Weber carb. Without the computer connector that used to be on the stock carb, the computer kept messing with the ignition timing to compensate...it was ugly. Now it runs great! It's not really difficult, either.

If you already have a Weber, all you need now is an HEI dizzy and you can TRASH all the computer and controller stuff!

I did did this by pass. Put on HEI and MC carb runs much better and no issues with starting the beast either.

Me and a friend of mine went ahead and did the bypass today and my Jeep is running horrible now. Everything is wired up correctly and the timing was reset, but I don't have any power. When I try to accelerate, the engine bogs down bad. I believe it is running a little smoother, it just doesn't have any power. The only thing that I can think of that could be the problem is the carborator. Like I said before, I have the Weber 38/38. I think it was running a little rich before and needed to be adjusted, but the jeep had a lot more power before I did the bypass. I took a look at his jeep that he had already done the bypass to and it doesn't even compare. He's running the old Carter carborator and when he gives it the gas, the engine acts like it wants to hop out from under the hood. It has way more power.

How did you reset the timing? You can't use the settings you used before the 'nutter'. You shold be around 9* at idle (500-700 RPM) with the vacuum line disconnected and plugged.

Would this help an 81 CJ7? The comments says it rewires it the same as a "'78 to '82 CJ "?

It's an 83' CJ7. It's set at 9 with the vacuum line plugged.
