Carburetor Replacement

I've been told that I need to replace the carburetor on my 1990 six cylinder.
Any thoughts on which is the best replacement carb that will be a simple swap without problems? On a tight budget here so maybe I should ask which is the best for the money.
Thanks in advance for any help!

well no carb is cheap...if you want a carb that'll do its job and last your looking at 250 and upward i went with weber 34/36 DGEV i believe if i remember correctly i found it new on ebay for 270. i would recommend it some say the motorcraft is easy to deal with i wouldnt know. but try carbs direct or ebay and watch for a good deal. hope this helps

We just put a 32/36 Weber on my buddies CJ-7 with the 258. The Weber is a pretty simple carb and easy to adjust. We couldn't figure out why his motor didn't have any power though. Then we found 4 bent push rods. I'm sure that will help clear up the lack of power. Though I was very surprised the motor even idled as good as it did.

I had expected to be in the $300-$350 price range.
I just want to make sure it's a good dependable carb and that the swap is easy and simple with no modifications required.

yeah in my opinion the weber was eaasy to install and runs like a champ. could damn near poor water in it or turn it upside down and it'll still run (joke dont try) but in all serious ness the only mod that is needed is a fuel pressure regulator cuz our stock fuel pump has to high of an out put i think its like 9psi and weber requires 2.5 to 3 psi ive yet to get the regulator on there and mine works fine just a little rich

You will get lots of opinions. I would go with the motorcraft. There is a guy selling the kits on Ebay with everything to bolt it on the jeep. It is also calibrated for the jeep. I bought a new Weber 34 and hated it. The jeep ran great but didn't have the power and torque I though it should have. I went with the Holley 350cfm 2bbl. I love it, great mileage and awesome power.

I've never seen anyone who wasn't happy after installing the MC carb. I even remember people saying they got an MC carb for 25 bucks at a junk yard. So, if money is the issue, I'd probably go with an MC. I decided I wanted something new on my twenty year old jeep and got a weber 38 DGES. It was pretty easy to install. Mine got a huge power increase with the swap. I think I paid 350 for mine.


By the way, who told you you need a new carb? What is wrong with the old one? Most people change the carb because they don't like the Carter, but alot of people rebuild them and have very few issues. I ended up breaking three small parts on my carter and got tired of how much trouble it was finding good replacement parts, so I did the swap.

I'm currently doing the Motorcraft swap. Found one at the junkyard for $20, plus $35 for the rebuild kit, and $14 for the adaptor plate. Oh yeah, forgot $10 for correct jets. Found all the information I needed here on Jeepforum. Can't wait to get it on the Jeep!!

Also the MC carbs do really well off road as they can take some decent amount of angle.

I was told by a mechanic that the carburetor body had so much wear in areas around where the rods go through, etc., that it couldn't be adjusted correctly. It runs just ok. Way too rich. Sometimes hard to start. Very sluggish acceleration.

Does anyone know what the fuel mileage is for the Weber 34 compared to the Weber 32/36? Also, performance difference, if any? Thanks

I know everyone can't get great prices depending on where you are, but I've seen posts from guys who got mc carbs from a pick a part and got it for 25-50 bucks. I think most rebuild kits are dirt cheap, like 12-30 bucks, but I can't say that I know that for the mc. I personally threw out alot for a new weber, so I'm only repeating what I read. I am glad you are happy though, I hear great things about that conversion and I understand it's much better for wheelin!
