A Muesum that had the car before the owner took it back had put a zenith carb on it. Not running when I bought it. Cleaned the Zenith and put it back on but but notatpoint of trying to start it. I talked to a guy at the Muesum who’d told me about the carb. Anyway, he is a model T guy and someone else told me the Zenith might be off a Model T. Thanks for the info.
As I recall, Adam Ford has a cast iron Zenith Model A on his A-22...Interesting thing with those carburetors are that the choke control rod has a duel function it will operate the choke and when twisted will adjust the Hi-speed jet.
