Do you know of any other years or makes it would fit? Edit, correction it shows 1930 also Regards Dave Edited November 12, 2022 by 30DodgePanel (see edit history) Link to comment Share on other sites More sharing options...
carbking Posted November 13, 2022 Share Posted November 13, 2022 That is the extent for production. Jon Link to comment Share on other sites More sharing options...

Mark Gregush Posted November 13, 2022 Share Posted November 13, 2022 Doing a quick thumb through of my 1925-1930 RADCO Carburetor and Motor Tune Up Manual, I do not find a listing for any car that would have had a Stromberg U4 (including PA). The biggest I came across was a U3. The 4 would indicate the size of the passage at the throttle butterfly. Wonder if this is for a truck, my books don't cover trucks, just cars. I am just posting what I found and will bow to more learned minds. Link to comment Share on other sites More sharing options...
carbking Posted November 13, 2022 Share Posted November 13, 2022 Ed - Branham lists the 1930 model C beginning production in January 1930, and the 1931 model beginning production in September 1930. Mark - The Radco manual you mention is an excellent reference for what they list, but not comprehensive. In addition to the production U-4 for the P-A, Stromberg made some experimental models for Auburn and a few trucks that did not see production. The production U-4 is Stromberg A-13774, P-A 734437 Jon 1 Link to comment Share on other sites More sharing options...
Aussi John 1 Posted November 14, 2022 Author Share Posted November 14, 2022 Hi Thanks for your helpful comments, does anyone know what other makes and models the U4 may suit. It appears from my research that that the U 3 and U4 are similar as the they take the same kit. I have two U 2 carburetors, which I would like to sell.

John The U-3 and U-4 are similar but two different sizes. Are those U-2 potmetal or cast iron ? Paul Link to comment Share on other sites More sharing options...
