I found this thanks to a few posters in a different thread and at first glance it looked great but the more research I do, the more I find people having problems with it and the mods necessary for it to work right.

A few people said they had to replace their fuel pump with an electric pump and add a fuel pressure regulator.

Also, it seems this isn't actually made by Weber. The “WEBER” name is currently owned by Magneti Marelli of Italy. This international company owns many other brands – the most interesting of which is SOLEX. This product is made by SOLEX and they slap a sticker on it, repackage it and call it a Weber... totally legal.

Overall, what do yall think?
 
I guess this is for a Jeep?

My experience is biased towards Toyotas, but I have had excellent luck with Weber Carbs. I have done more than a couple, just finished up putting one on the 87 FJ60. Really wakes them up and makes things so much simpler and easier to diagnose without all the emissions junk.
 
Bad call on the 34. I've heard nothing good about it. Yeah, it's an old Solex casting, and apparently pre-worn-out at that. I used to know a "Weber guy," a real genius with them, and he absolutely hated that thing. Ditch it and get a 32/36 or 38 kit. Or, even better, go FI. The new Webers aren't what they used to be. Chinese made and hit-or-miss at best on quality. Sometimes you get a good one, but sometimes you don't. I just installed one on a Tracker 1.6, and it worked well, but it's still a carb.

Thats what I'm hearing but isnt the 32/36 or 38 made by a fake weber as well?
 
"Weber" isn't Weber anymore. Weber Italy quit producing these carbs a long time ago. They opened up a plant in Spain. Many people said the quality dropped then. The Spaniards went on strike about 6 or 7 years ago, and never started production again. They closed the shop. For a little while, the only Webers you could find were what was in stock on shelves when they closed the shop. Then the Chinese, specifically Empi, bought the castings and rights to the name. Now people long for the quality of the Spanish castings! Either way, it's what you can get now. The 32/36 and 38 are at least based off Weber carbs, and still work well for what they're designed for. The 34 is some bastard child, and should be avoided.


BTW, all this info is the best of my recollection. I'm sure a quick internet search could prove me wrong on some of this. But I remember the panic when they went on strike, and I actually have an old Italian Weber that I may use someday.

Thanks, I figure, if its good quality and improves my Jeep, I dont care who makes it. I'll look at the 32/36
 
The best quality improvement you could make would be to convert it to FI using parts off a later Jeep or one of the kits available. The 32/36 is going to piss you off if you wheel it, as it floods out in off-camber situations. Depending on which direction it's mounted, it could be goign up a hill or down a hill can flood it out. I could hit the brakes hard enough when I had one on my Sammi that it would stall. Driving down Daniel was downright scary, having to stop every 20' and crank it, then feather the clutch and gas while standing on the brake to keep it from dying. All the Webers are going to be a compromise. I've heard the 34 spills gas all over itself. I don't think the 38 does that, but your economy is going out the window. Unless it's just a street or mud truck, I'd seriously consider putting that money towards FI.
 
Ok so I really like a FI system. It seems which ever way I go, they all have great reviews. I just have to decide which one would help out my stock engine the most. Here is what I've found. Let me know what yall think about these and the pros and cons.

Howell Fuel Injection Conversion Vs. the Mopar MPI Fuel Injection.

There is almost a $1000 difference but all I can find is that the Mopar has a more advanced computer system, fuel and spark control, offers more control/drivability. That sounds nice but will it make a huge difference? This is my daily driver so if it did make a huge difference, I would fork out the cash.



Thanks for the help guys!
 
This is now beyond my scope. I've never messed with Jeep FI conversions, I just know it's a better option than a Weber by far, especially if you plan on actually wheeling it! I'm sure most people would tell you to go the junkyard route, but you kinda have to know a good bit ahead of time to make sure you get all you need, and it can still be confusing. I've also seen Chevy TBI conversions that worked well, but took a lot of time and knowledge. I've heard good things about the Howell, but don't know that I've ever seen one in action. And I don't know a damn thing about the Mopar kit. I do know that a good running 4.0 should have all the power you need to scoot up and down the road.

Thats what I'm thinking. I have a 4.2 so I dont need any more power really. Its my daily driver so i'm thinking about the Howell. Ive heard mix reviews from the Webers so it kinda scared me away. I'm thinking the Howell is the way to go as of now. I'll probably get around to doing it after March so I have plenty of time to decide. Just wanted to get a few people's opinion!
 
I agree with the FI swap being the best. If you can't afford it right now and your BBD is killing you, consider grabbing a motorcraft 2100 with a 1.08 venturi from a boneyard, throw in a rebuild kit, and bolt it on with the mr gasket #1937 adapter. All you need to do is bolt on a little piece of scrap to the throttle arm to make the linkage work and get an air cleaner that fits. Most guys can do this for under $100. Pair it with a junkyard HEI swap and that 258 will run great. Theres tons of write ups on the net about both.

Good Luck

i have the same jeep as you and ran a 34 webber for about 5 years and had no trouble at all,other than when climbing it would stumble. i would really have to stand it on the back bumper (literally on the bumper,it's a pipe bumper and grabs sometimes) to have any stumbling problem. there might be something to that story about them stopping production for a while. i looked at them and didn't buy till several monthe after pricing one.the price went from about 200 bucks to over 300 and at one time they were way over 500. i still have it sitting on shelf,i went to propane. when i installed the webber i didn't have to change or do anything other put the carb on it and go. i also still have the instructions and all paper work on it if you want it.haven't really thought about selling it but if you want it i don't guess i'll ever need it.
 
the 2100 w/hei setup is good, but for a few $$ more, if your're talented at the junkyard or even craigslist, i'd go for a fi swap from a 91 or later xj or a zj, grab the intake, throttle body, all the sensors, wiring harness and computer and your set, they're all over the place for ALOT less than the mopar mpi and they are essentially all the same parts, but much cheaper-you'll know the difference over carb with your gas mileage and the first way steep climb you come across
