Reply To: Resizing UU-2 main jets

[Mark Wetherbee]

Thank you Ed, as I mentioned I spent a good amount of time with John and he went through the UU-2 specs with the book in front of him. The UUR is the correct one and was most likely used to replace the UU because of volume but I should be able to get this to run right. It spent a long time in use ultrasonic tank and has all the passages are cleared out which I think was a lot of it’s problem, plus it’s missing one idle channel hole washer which I can get from Cislak once I get my full list of parts I need together. The carburetor is in real good shape considering the pot-metal issues of that period and if I’m lucky enough to trip across the UUR at a reasonable price I might get it, but there again it might still have the same internal needs as a UU… fits Bugatti and Dusey, why couldn’t it have been Buick and Chevrolet?
