NCB just so you know the feedback carburetion set up on late CJ7 and early wranglers is a FORD design. Running a FORD ignition module and pickup coil, and running an almost stolen FORD carburetor.

for some reason jeeps have always lagged behind in engine technology. They did away with the feedback system like that in the 80's. apparently they were very picky and hard to keep running right..... but they did solve some emissions problems.
