Just bought a jeep. Leaking carb, What rebuild kit?
 
Hello I just bought a 1987 Jeep Wrangler I think it has the 4.2 I6 with manual tranny. Seems to be stock with 130k miles on it.

The carb is leaking on the right some somewhere. Think its one of the gaskets near the base of the carb.

I want to rebuild the carb now because the car runs like crap. Stalls 5-10 seconds after I start it. Only runs on high RPM's.

Do I have a 1 barrel or 2 barrel carb?

Will this kit do?

Kit, Carburetor 8134232

Replace it with a MC2100, and don't look back!

$300 is a bit much for me to spend right now.

I was just thinking about buying a rebuild kit which is around $20 and do the BBD idle fix.

Will this work?

I dont even know the Jeeps runs yet because I just got it and it hasnt been running properly.

X3, got my MC2100 for $20.00 at the junkyard. Rebuild kit was $15.00

The Mr.Gasket adapter #1937 was like $10.00

This carb is really easy to rebuild, I never rebuilt any before it, & just rebuilt it again after two years. I didn't even have to think about what to do, my hands remembered!

Please don't waste any time on that BBD, removing it & tossing it in the trash is more than enough effort spent on it.

Do your research, & get all the crap together first. & get one with the 1:08 venturi. (Listed on the drivers side of the fuel bowl.)

I bought mine from that very same guy. It was super fantastic easy. his documents on changing it are detailed and easy to follow. I first bought a rebuilt carter from advance auto. put it on. it ran way better actually started and idled perfectly maybe a little stumble here and there. all was fine till I took her for a drive. Oh what a pig no power on the hills bog down under any load or strain it was terrible! I did not know what to do. so I began reading on here about carb problems and superscribed to all the jeep catalogs out there. of course I was very close to getting the Weber carb. It seems most of the forums speak of the MC2100 or 2150. But suprisingly the catlogs do not mention a word of it??? I suspect they can only sell new carbs not rebuilt ones?

Anyway bite the bullet and get the MC2100. it clears so much under the hood and makes it not only look neater and is so simple to work on in there not all the vac line hoses running amok. much less intimidating than it all seems if thi sis your first time working on a vehicle.

If you want to save the money do what buckshot says. for less than $50 you give it a shot. Just be careful of what you do under there. Like I said the ebay guy might be pricey but he has all the documentation you need to build it and his carb is already rebuilt ready to go.

Your choice but believe me going with the MC2100 has been the best thing i did so far.

Cheers, and good luck

Buying an MC2100 that someone else rebuilt, would be silly.
Way too easy to do yourself, & you'll need to do it again after 2 or 3 years.

Everyone worries that they've never rebuilt a carb. All your gonna do, is take it apart, clean it, & put it back together with new gaskets.

You'll find one locally (Junkyard) & it will prolly have the correct jets, as jet size is determined by local altitude.

You will likely need a bigger power valve,(P/V)but that's easy cause the MC uses Holley P/V's.

The rebuild kit comes with a 7.5HG P/V. mine needed an 8.5P/V, which I got at a speed shop.

Here's Holley's vid that shows how to figure out which size you need.
YouTube - Holley Carburetor Power Valve

A hand held vacuum gauge is cheap, & will come in handy.
I got one at the big box auto parts, for less than $20.00

I also have a timing gun I got at a yard sale, big help!


If you decide to do the MC, I can help you with any info you need.

If I don't have it, I know where to look at http://www.jeepsunlimited.com
for answers.

Best thing about this mod, is you get another rebuild kit, & a can of carb cleaner spray, to take on wheeling trips.

If it needs to be worked on, you can rebuild it on the side of the trail.;)
