carbking Posted October 22, 2023 Share Posted October 22, 2023 In 1929, Chrysler used a Penberthy (a.k.a. Ball & Ball) model DB-20 carburetor. In 1928, Chrysler used a Stromberg UX-2 on the EXPORT model 72. This is the only UX-2 listed in the Stromberg factory records used by Chrysler. Good luck on finding the DB-20; the castings were unstable zinc alloy, and have disintegrated to dust! Jon. Link to comment Share on other sites More sharing options...
BlueDevil Posted October 22, 2023 Author Share Posted October 22, 2023 Thanks carb king. I have a DB-22. What is the difference? Link to comment Share on other sites More sharing options...
carbking Posted October 23, 2023 Share Posted October 23, 2023 I don't know. I have a couple of non-useable DB-22's that I bought for sample components for rebuilding kits. I have NEVER seen a legitimate reference for the DB-22, although there is an ebay vendor that has one which he/she claims is a rare racing carburetor and wants a small fortune for it. Penberthy literature is more scarce than winning an argument with the IRS. I have no literature on either the DB-20 or the DB-22. A.E.A. does list the DB-20 as being correct. I would suggest a couple of paths, depending on your expectations for the car: If a show-car in national car shows where the car can be trailered to the show field, or a museum car that will never be started; epoxy all the cracks in the Penberthy, paint it gray, and block the fuel line so fuel cannot enter the carburetor. If you plan to drive the car: (1) Have new aluminum castings produced to rebuild the DB-22 OR (2) Use a different carburetor. Jon Link to comment Share on other sites More sharing options...

ipeeforward Posted October 24, 2023 Share Posted October 24, 2023 Bill, My 1929 75 built for export has a UX-2, as Jon pointed out it suffered the same fate as the DB-20 and dissolved. I have new aluminium castings from Australia. Not got round to assembling it yet. John 1 Link to comment Share on other sites More sharing options...

BlueDevil Posted October 27, 2023 Author Share Posted October 27, 2023 Here is the carb set up I am considering for my 72. Left is a Penberthy DV-22 which I am going to start with, middle is a Penberthy SV 37 (what the car came with) and the replacement BB-1 Intake view next, then top view with the DV 22 on the right.
