Switching Carbs?

Hello all. I'm new to Jeeps and just picked up a really solid 88 YJ this week.

Ive been working on tuning it up all week. The previous owner had lots of odd stuff going on with the wiring. Wires cut to the o2 and temp sensor I think. Along with other wires cut and put back together. I don't know what he was doing. But figured the best thing to do at this point is to get rid of all the computer controlled crap that I can and get it to where I can tune it all myself.

So I did the "nutter bypass" a few days ago. I got all the way to setting up the carb and the stepper motor seemed to be seized. And I'd rather just ditch it.

So on to my delema. The Jeep seems to run 10x better then it did when I 1st got it. But still has a slight mis.

Ive been looking at replacing the carb with a a non electric one. Ive found a few switch kits up on ebay for the Motorcraft 2100/2150 and a kit to switch to a Weber. But I have also found an old non electric Carter that has been rebuilt.

Is a Motorcraft/Weber all that much better then a non electric Carter? Are they really worth the 200$+ difference in price?

Thank you all for your responses.

My 2 cents.

Hi! from all the carters BBD that i've rebuilt, the last Jeep I have has a Weber on it and I really like it compared to the carters. Mine also has the nutter by pass with a lot of stuff removed I'm still working on cleaning it up. i think ether one would be an improment Just my 2 cents. Good luck with what ever you do Joe100

I moved from the Carter to the Motor craft 2150 a couple months ago. Night-Day difference!

FWIW, if you take off the stepper motor and soak it in a little solvent and then work it a little, you can get it to move.

The needles are held in place by notches in a little plate inside the housing. The little plate is what moves inside the housing.

There are thousands of MC2100/50s in junkyards & they are super simple to rebuild.

I did my swap for 90 bucks total (carb, adapter, rebuild kit, etc) & it took about an hour to change them out.

I never had a carter but I went from weber 34 to a motorcraft to a Holley 2 barrel and now have a Holley four barrel. It's worth skipping to an after market intake an a four barrel. Easy to tune and runs great.

Well I found a 2100 with the plate and stuff used on ebay. Offered the guy 145$ and he took it. So it looks like I'll be switching over to that now. Is there any good write ups on switching to the Motorcraft carb I should read up on?

Often a miss has nothing to do with a carb. Stumble, flat spots, yes, but you might be barking up the wrong tree.

You can get a motorcraft from a junkyard, but it will probably need a complete teardown and cleaning, and depending on what it came from might need different jets.

You will be happy with the Motorcraft. When I had my 87, I went from a Carter to a Weber to a Motorcraft. The Motorcraft was by far the easiest to make run properly and it seemed so much happier with it on there. Make sure ALL vacuum lines are good and pay attention to the details of whoever's directions you use to convert it. You already have a good part of the job done with the Nutter bypass. I had several good links to the conversion, but like a dummy I deleted them when I sold that jeep.

I have an 88 YJ and I went with the Weber. The install went very easy. I ordered mine from Weber and got it and the linkage kit for $189.00 with free shipping. I have had it on for three months now and I have no complaints.
