edinmass Posted December 17, 2021 Share Posted December 17, 2021 Unless you have one of the 10 reproductions, that carburetor is not safe to run, the car WILL burn if it's the pot metal unit. Run a Stromberg UUR2. Link to comment Share on other sites More sharing options...
Mark Gregush Posted December 17, 2021 Share Posted December 17, 2021 Why would the metal used to cast this carb be any different than the millions of carbs made by Zenith in the same era, cause the car to burn? Unless you are talking about later having warping issues? Some do, some don't. If the top is warped over the fuel bowl, there are work arounds. One might be to use the UUR2 if it can be found.

carbking Posted December 17, 2021 Share Posted December 17, 2021 Ed - the 105D is the earlier brass, the dangerous ones are the zinc alloy 105DC. Jon. 1 Link to comment Share on other sites More sharing options...

Mark, my bad. I was off by one letter, and was only referring to the diecast units..........it seems multiple companies in late 1928 to mid 1930 were using a bad formula for their products. I would not be surprised that they were all sub contracted and made by the same injection mold company. Stromberg, Zenith, Stewart Warner, Delco, and a handful of others all suffer from issues with parts made on those dates. I will stand by that the 105DC’s are the ones that seem to suffer more than any of the others, and they are so bad I would never use one. Some of the UU-2’s with the early uppers are also as bad as the 105DC’s also. Simply put they are not worth the risk of burning your car down to the ground.....and they will burn. Carbking hasn’t serviced them for years.......with good reason. as far as UU-2’s and UUR-2’s being found.....we have a dozen each of GOOD units available. Not cheap, but we guarantee our units.

edinmass Posted December 19, 2021 Share Posted December 19, 2021 Sorry to hear they are out of production. Unfortunately many projects that are still needed now and in the future won’t ever be done again due to economics......and lack of interest. I never got to see one of your units at George’s place unfortunately. I missed the Stutz event at Hilton Head, but did see you at the Hershey dinner. Merry Christmas......Ed Minnie.
