Weber Carb for my 89???

Ok...not saying anything new, but the stock Carter Carb blows... I've heard from buddies that have them that getting a weber will solve some problems. This sounds a lot cheaper than going with an EFI conversion kit...If it works. Anyone smart on the issue? If this is a good sub...what kind of specs do you recommend?

We put the Weber 32/36 on my son's 90 YJ in April and did the Nutter bypass at the same time. The Jeep runs like new and no adjustments to the carb were necessary. Very simple bolt on job.

Bypasses the ECM so it will let the carb do its thing without jacking everything else up. You'll also have to change your timing.
check this out for the nutter-

EDIT: This is what I got, came with almost everything, its the same thing as above but with the proper adapter plates

I think the very first thing I did when I got my heep was replace the carb with another stock carter carb...but an older one(one for a CJ) to eliminate the electric part on the back. So does the electric choke on that redline carb force me to hook it up again?

you dont need to plug the big connector thats on the back of the carb. the electric choke is run off a single wire and connects on the passenger side of the carb or the side near the valve cover.

All of this is very good advice (advice I went off of actually....), but mine required much more work after the Weber - found out I needed more fixed and was just hitting the "tip of the iceberg". After the Weber, I ended up replacing the fuel lines, fuel filter, ignition coil, spark plugs, plug wires, cap and button and finally turned out to be the distributor - NOW it runs like a top......

Just an FYI that the Weber may not be the answer to your prayers like I thought it would be for me......

It will answer A LOT or your prayers, looking back I would NOT have done nothing until I had put the weber on, the Carter will never run right an will aggrevate you till you finally get mad enough to do something stupid like sell your jeep, I almost did.....finally spent the 365 shipping included to Canada....and 3 hours in the driveway, and POW, fired up first time, and never missed a beat since, I to had to change the Dist, and wires and plugs, but the weber just higlited the other problems cause it was at least finally wanting to run.....runs like a top now

on that note also I did the posi lok to get rid of more vacuumcrap, so now I only have 3-5 vac lines under the hood, instead of the speghetti platter it was with the carter...

Just an opinion, but have you considered a motorcraft 2100 for a carb? I've had both a weber and a MC on my '90 4.2 with 4.0 head conversion and though the Weber runs great (once it was tweaked and fuel pressure regulator installed), I never thought that the MC was a bad alternative-rock solid running at just about any angle, no computer interference, relatively easy install with little to no tweaking, and most importantly CHEAP!!! I got my hands on a Weber from a friend and I wanted to try it out which was the only reason I took off the MC. I keep it as a spare in case the Weber ever craps out.
