My Nutter Experience. Praise Nutter (and Luckycheesehead)!

Hello fellow CJ'ers, just wanted to share my Nutter experience.

My 85 CJ-7 was having idle issues, missing issues, and loss of power issues. My mechanic (on this tiny island I live on) suggested a new carb, then I learned about the Nutter bypass.

I brought him the Luckycheesehead instructions from this site and he got it done. Woohoo!

The first 40 miles it felt like a new ride, I couldn't believe it. But then it started bogging down again under load. But the idle was still great. My uneducated guess was I really did need a new carb or the new vacuum advance was leaking.

Today I went to the store to buy some carb cleaner. I noticed and grabbed a bottle of STP carb cleaner and poured that in the fuel tank right away. That seemed to instantly help, or maybe it was just a coincidence.

Anyway, got home, took the air cleaner assembly off, gave it a good cleaning, taped up the "T" where the Nutter vacuum advance was spliced into the vacuum line, and shotgun sprayed a bunch of carb cleaner down the throat of the carb. (I don't profess to really know what I am doing.) I also put in a fresh air cleaner filter

The result.....AWESOME! It's better than when I left the shop yesterday. It hauls up hills without losing power or missing. The throttle response is instant.

I drive daily on dirt roads they could test lunar buggies on. I also have to drive up some curved, dirt hills to get home. I don't need to off road, my life is off road. I suspect I will have to learn to clean the carb on a regular basis.

Thank you Mr. Nutter, Luckycheesehead and the rest of Jeep Forum.

It is a way to make the computer controlled engines run like yours is already set up so it can't help you.

Here is the link anyway, it has vacuum setup info also:

I have done the bypass twice and both times it made a real difference in the way the CJ's ran. A real improvement.
