304 Carb Suggestions

I bought a 80 CJ-7 about a year ago. It has the 304 and the 4 speed. It looks like someone put a holley carb on it but only information I can find on it shows its from an old Ford truck. What carb would you recommend I buy for it? Thanks

If it's still a 2 barrel intake I'd go back to original Motorcraft. They're great carbs.

Not in my opinion.

I'd get it from it National Carbs. Every carb they sell is dyno-tested and comes with a good warranty. And their customer service is top notch.

I may be wrong but I think the 2100 was stock and the 2150 had the bigger venturi... ??? Not a carb guru tho

Is there anything wrong with the current carb? Just wondering if a rebuild might save you some headache if you have to swap a bunch of linkage and what-not to get a MC on there.

Yep.

They will also custom configure your carb to your engine's specifications, including jetting for altitude, no extra charge.

Agreed. Here's their description of their carbs:

"In order to provide you the highest quality remanufactured carburetors in the industry, each carburetor is individually built by our certified technicians using a master rebuilding kit. All other components are cleaned, tested or rebuilt to meet O.E.M Specifications. The base plates are rebushed to remove excess wear from around the throttle shaft to stop certain vacuum leaks. All bolts and linkage parts are zinc plated. As well as casings are tumbled to chrome like finish. Or by special request, Dichromate finish can be applied.

We recalibrated the carburetors for today's gas and remove the inherent problems like hesitations, flat-spots and hard hot starting. Every carburetor goes through a 3 step testing process, first a float bench and pump test, second a dyno flow bench test, and then a live engine test. All the adjustments are set for a bolt on and go carburetor."


You won't get that level of manufacturing from the "ebay guy".

I love the holleys. We have ran them on our race cars for years and are virtually trouble free and easy to work on. Most rebuild kits are in the $20 range and easy to put in and adjust. Id go with that option if it were me, saves money and time and headache with putting a different style on it.

Thing with tge MC2100 series is that they are one the best carbs for off road use... almost no problems with off camber and steep inclines. Sure a holley is easy and cheap for a car on the street or track but even the truck avengers aren't as reliable on the good hills.

The carb on it now floods very easily on any incline. I had it rebuilt once by a friend and it didnt change much. I dont mind spending a couple hundred bucks on it if it makes my jeep that much more reliable. As far as modifications to make it work, what would I have to do?
Thanks again

Also, what kind of choke would I want? It says the options are climatic, electric and compenstator value?
