I just received my shiny U&J carb from Stan Howe, it looks fantastic, two more in the works, thanks Stan.
Rick, what's the story on U&J carbs? I haven't seen anything on them before. PK
Pat, Stan tells me they are one of the best aftermarket carbs for the T he calls them zoomy zoomy I am building a improved HP unit,
Improved is an understatement. The are a hot carb with the advantage of being virtually trouble free. The big problem with them is that virtually every bowl is cracked to the point of being unusable and since they are built on some antiquated measurement system nothing else will fit. I machine the body to accept a Holley G bowl and recently bought a tap and die set to make new bowl nuts and rethread the stem to fit. The venturi is often broken and I make new venturis for them from aluminum. Since no other needle and seat fits I make a new needle and seat set. But they run great when you get them done. I have two more to do for Rick and two that are sold that need to get in a box and go down the road.
I own what is probably the only new old stock one in existence, part of that deal was the original choke setup that came with them when new, Mike Lebsack and I reproduced the castings so I now have the original style choke for them. The manifold is very hard to find so I am making an adapter to use another manifold with them.
Lots of work and fussing with them but worth it when one is all done and running.
Pat, if you look around on my web site www.strombergof.com, you can find more pictures of some U & J's.
One up for auction as we "speak":
Speaking of the U & J and its choke, I find that the U & J is cold blooded. With a cable operated choke I am able to keep it running with partial choke until the engine warms a bit.
It is a great carburetor / intake setup. So far only a Winfield has provided better performance comparing the two setups on the same car. The Winfield setups are rare and costly, the U & J is much easier to find.
Which Winfield size do you use?
It is (I think) 1 1/8" updraft with the matching Model T intake manifold.
In order of performance, I would rate the Winfield as the best, the Miller Master next and the U & J next. In the order of fussy and troublesome the Winfield and Miller Master would be right close to the top with the U & J close to the bottom. Once they are set up and adjusted they are trouble free in my experience. I ran one on my speedster for a long time and loved it.
You do have to be careful when buying a U & J. They made them for quite a few cars including the Overland and Star. Those carbs are somewhat different than the one for Fords. The Overland version has the flange turned 90 degrees and the throttle shaft perpendicular to the centerline of the engine.
U & J also made a real nice "foot feed", or accelerator pedal kit. It was all nickel plated with ball jointed linkage.
