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.
