carter stepper motor / computer question
On a 83 CJ with the 258 what does the computer control besides the stepper
motor on the back of the carter carb? My stepper is not even connected,
what is the nutter bypass going to change? Also attempt #2 at getting the
MC2100 carb is going to happen soon.

Re: carter stepper motor / computer question
It also controls the timing advance via a knock sensor and any other
electric/vacuum modules like the fast idle kick up if you have an auto
or AC.
Basically if the carb is unplugged, it has gone into 'limp home' mode
with the timing clamped down.
When you do the 'nutter' the timing jumps about 15 degrees with the
ignition module running things like it is 'supposed' to do.

Re: carter stepper motor / computer question
I have gone 4+ years with no stepper and it seems to run ok. But that could
explain why occasionally when I first start up the Jeep it will run super
rich until I turn it off, and restart. I bet the computer is messing with
the advance. I will have to take care of that issue soon. Thanks Mike.
