|Nubby55||I did the By-pass and all was so much better, and then I change the Carb. to one for a late 70s early 80s CJ7 with no stepper motor, bolted right on every thing hooked right up NO MODS no Adapter plates, and runs like New!|

Good luck, man! It's super easy once you get everything figured out conceptually. Here's my thread that I started when I started the project out... Sadly, I didn't really get any help with it - but I documented what I did and anything I ran into pretty well so that others with similar carb situations could have some help. Don't know why I JUST thought of it.

|indirocz28||Also, do not adjust your air fuel fixtures without a wideband o2 sensor so you don't cause more issues by running lean/rich. I know its a crazy thing to have on a jeep, but you can make it so that it is modular and use it for several different vehicles.|

No. You don't have to worry about it. Though in your case the bypass is "needed" You computer is trying to get information from stuff and control things that aren't even there...
When I got my YJ it has a carb off of a '72 Dodge (Still the Carter) which I didn't figure out until I was doing the bypass as well. Make sure everything else is hooked up and connected the way it should be according to the bypass instructions. It ended up making a world of difference for my YJ.

|combsn87||so i started this you know, dug in cut wires and what not..and found out that my carb was already bypassed. but not the same way. If you look at picture 4 there is a plate covering where the stepper motor used to be. so i am guessing i dont have to worry about the ecm controlling the carb?|

That is the stepper motor plug. Those bottom screws are to adjust your fuel/air mixture.

one other question. on 4x4wire is says this..
The following steps all apply to anyone keeping the BBD carburetor. Steps one and two may be skipped by those changing to another type of carburetor or to fuel injection.
are the idle jets these?
and is this the plug for the stepper motor?
Just want to make sure before hand.

About to do the Nutter Bypass
Can some one take a quick look at my carb and help me determine if it has the Carter BBD carburetor?
