Any suggestions for an upgrade on the original Carter WO carburetor? Possibly a two barrel with a dropped round air filter? Looking to get a little more oomph out of my baby.

I put a 2 barrel Rochester carburetor on my first 2A a long, long time ago.  I had to make a new intake manifold to adapt the carburetor to the Willys.  It did run  stronger, but I'm not sure that it was worth the effort.

Adding a 2-barrel carb may not necessarily improve your performance - in fact, it can hurt it. There must be relationship between the volume of air drawn into the intake manifold every two revolutions (i.e. all cylinders during one functional cycle) and the size of the aperture (at the throttle plate) and size of the venturi for the carburetor to work efficiently. For example, if you put a large 2-barrel carb on a 134 cubic inch engine, and tromp on the gas pedal, the vacuum drops to zip, fuel cannot be drawn into and through the venturi, and the engine comes to a halt in a heartbeat. WOs are fickle to set up, but they are efficient and the barrel and venturi are sized properly for an L134. Joshua is right about the Solex - especially in cold environments. ...R

You can spend an obscene amount of money for a performance head, header, resonator, intake manifold, carburetor(s)  and yes, you could even turbocharge the little beast. You might even get lucky and manage to get your hands on some parts actually made for the 134. But it would still be a CJ. A lot of money for very little real performance and investment return.  Or, you could find yourself a small V6 and go hog-wild with drive-train upgrades, a lift kit, monster wheels and tires and, well, IMHO, you won't have a jeep anymore.

If you need more oomph, you may be better off boreing the engine 30 thou or so.  Mine is 60 over and I believe I can feel the difference.  It won't go any faster, but it does feel stronger on the long pulls than it did before.  I stayed with the carter after trying a Solex, if the Carter is set up right it seems to do a good job.  There is a package that I've seen that includes a manifold and a two carb set up, its two Carters, smaller than the WO on a single manifold, complicated linkage, but reminiscent of the old 6pack configuration on the Cuda.  Try to PM Gopher 4x4, he can tell you about his.

A fresh motor with excellent compression will have more snap than an old worn out one for sure.. Good ole WFB RIP   rebuilt his Mule motor last year I think it was, and when it was done it was like a hot rod compared to what it was like before.....
 
There was a head upgrade called the Willy Willy head IIRC that upped compression and may have had a few other mods, I would try a little compression boost before going for an unknown carb swap. It has been discussed before here, the Supersonic head is another more common head swap. Try advanced search for  milling head  or supersonic....I dunno if we ever got a conclusion as to how much you could get away with milling off a stock head ...
 
In general if I was to do the 2BBL I would look for one that has a similar or smaller primary throat and  more throttle bore area when in 2BBl mode, MAYBE a MustangII or Pinto Holley Weber...
 
Good luck, report back your results if you would, it will help others looking for more power too.

Last I heard Louie was experimenting with two genset carbs on a dual manifold.

Well lets see, the Jeep will be reasonably safe at 50 mph sooooo just how fast do you want to get to 50 mph and what is it worth to you?????? If you want a Jeep that is faster to 0 to 60 just buy a newer Jeep and don't bugger up an antique Jeep. I have not had a problem with how fast my Jeep gets to my max of 50 mph and it's not like I am racing someone at a stop light. 

If your looking for more power on a hill your not going to get it out of the L134 without a lot of money thrown at it. I suggest you drop a Chevy 350 with say, dual four barrel carbs or fuel injection and see how long the drive train lasts with that.

Sell the Jeep and buy something with the power you want.

Thanks for all the input guys! I was just curious about an upgrade. I still love my jeep, and there's no way I would sell it just for a little more power. I'll happily drive down the street going 43 mph then give up my Willys. I think I'll steer clear of any kind of upgrade. Might just rebuild the Carter or save up for a new one.

about ten years ago I bought a rebuilt one from Peter Dibella - not sure he is still pushing parts but it hasn't given me a problem since I bought it

I recently discovered this and am looking to get one since my aftermarket 1 barrel has gone south. Some ethanol fuel no doubt.

Mixture is turned just about all the way in and the fumes will still get to me.

They are both correct. 134ci, 62hp on a good day. I know you can move a mountain with a sewing machine, but that is more to do with the gearing than the motor. The Go Devil was not designed for much more than a rough dirt road. Highways didn't exist when it was designed in the 1920's.

I responded to a guy who posted yesterday, with my opinion on what he was contemplating. The others responded with their opinion to the same poster. Yes, the old thread was "resurrected", how does that hurt you? I'd say it's good to bring up some of this old stuff, so the new guys can learn from it.    BW
