Reply To: Stromberg UU2 carb on ebay

[Edgar Minnie]

Venturies are wrong size, both large and small, as well as idle circuit tube, main jets, air bleeds, choke and choke horn, economizer valve, idle discharge tube, linkage, idle mixture screw, idle channel holes, and several parts of the casting are different. (There are no less than 5 main body castings and three different upper castings.) A Pierce engine is either 366 CID, 385 CID, and the 1930 model C 358? But UU-2 carbs were built to run on engines from 198 CID to over 500 CID. SO yes there are huge differences from one carb to another. You could easily spend 700.00 on buying correct parts to convert it to PA. Add another 400.00 if you need another choke horn. It’s cheaper to buy the correct carb than to install the wrong one and burn a valve running lean.
