K8096 Posted November 28, 2013 Share Posted November 28, 2013 Can someone tell me the main differences between the Stromberg UU2 and UUR2 carburetors? I know they are the same basic design, but is the UUR2 just a larger model of the UU2 for larger displacement engines? Link to comment Share on other sites More sharing options...
Buffalowed Bill Posted November 30, 2013 Share Posted November 30, 2013 I have been told that the UUR2 was an upgraded version of the same basic carb with additional use of brass in place of pot metal. UUR2 carbs seem to be much sot after. Link to comment Share on other sites More sharing options...
edinmass Posted December 2, 2013 Share Posted December 2, 2013 (edited) There are quite a few differences between the two carbs, a UUR2 is a much better product. The bodies are different and don't interchange. Both were installed on cars from 240 cid to 525 cid. They are often installed from Nash or Stude on PA's and don't run right. Also there are several different venturies sizes. The shop I work with makes more than 100 Stromberg updraft parts. I deal with these carbs every day. I can help you in more detail if needed, PM me if you like with your phone number. PS The only correct application for a Stutz is the UUR2 per the factory Stromberg book, we have built them for both left and right hand drive Stutz cars.

The shop you deal with do they have a web site or an address and number I can get in touch with them? I could truly use the help.......Thanks Link to comment Share on other sites More sharing options...
K8096 Posted December 10, 2013 Author Share Posted December 10, 2013 I assume the shop he's referring to is Classic & Exotic Service in Michigan. They have a website and sell carb parts listed on e bay all the time too. Link to comment Share on other sites More sharing options...
alsancle Posted December 10, 2013 Share Posted December 10, 2013 No, Brian Joseph in MI has lots of parts but he is actually referring to John Cislak in Springfield MA. Link to comment Share on other sites More sharing options...
trimacar Posted December 10, 2013 Share Posted December 10, 2013 John Cislak rebuilt the UUR-2 for my '31 Pierce, and did a great job. He makes a lot of the parts for these carbs, and knows how to rebuild them to match both the car and today's fuel. He's busy in his shop, so like a lot of things in this hobby, you'll need a little patience and a little more money, but it's worth it....Go on Ebay and just type in a search for UUR-2, he has a "Pierce Parts Store" and his contact information is in the listings.....

edinmass Posted December 11, 2013 Share Posted December 11, 2013 Hi, John Cislak's contact info is 413-543-9017 east coast business hours. His email is pierceparts@aol.com . He makes lots more parts for the Stromberg carbs than he has listed. Some of the stuff you see on other sites for sale are his parts. He makes parts for Stromberg UU2, UUR2, EX-22, EX-32, EE-3 and some others. He has upgrades for many parts and for E10. His small website has some of the Stromberg photos and parts listed in color go to piercepartsstore.com and you can see what he does. My best.

Povertycove Posted December 15, 2013 Share Posted December 15, 2013 Does anyone know what one of these UUR2 carbs are worth? There is an elderly gentleman here in Sarasota who has one, and asked me to find out how he could sell it. He used to own some large Pierces years ago, and had this one carb restored. I looked at it, and it seems brand new, but other than that I don't know anything about it. I'd really like to be able to get back to the fellow with a value, and a way to sell it.

trimacar Posted December 15, 2013 Share Posted December 15, 2013 I just "brokered" the selling of two of them (although technically it wasn't true brokering as I didn't ask to be paid), email me and I'll tell you the range. One problem with these is that they were used on a few Classic cars and even White trucks, so just about any one that a person buys is going to have to be rebuilt to match their car (jets and such). david.coco@comcast.net Link to comment Share on other sites More sharing options...

Both the UU-2 and the UUR-2 are TYPES OR MODELS of carburetor. The different INTERNAL sizes allowed them to be used by various manufacturers on engines from 198 to 525 CID.Jon.

edinmass Posted December 16, 2013 Share Posted December 16, 2013 (edited) As Carbking often has more information than anyone else, I stand corrected as to the CID that the Stromberg U series fit. I did not realize they went down to 198 cid. I was showing 240 in my notes. There are two different size choke horns with various choke set up with single or dual shafts, and so many different linkage set up's that it would make your head spin. I have also seen several bronze U series carbs with other changes to them. There are two Bugatti carbs in the shop right now, both incorrect applications, the super charged type 57 had a carb off a small displacement car and someone drilled out the large venturies with a drill press. It is unbelievable how abused and screwed up most of these carbs are. Edited December 16, 2013 by edinmass (see edit history) Link to comment Share on other sites More sharing options...

Please let me know what you think. Link to comment Share on other sites More sharing options...
