About the Zenith carb floats I found that the float from a Farmall H is the same as the float in the 75A carb. I bought just the float from a used tractor parts yard for $20.00. Has been working for about 5 years now. When I had the carb problem, I bought some gas from a country store that sells a little gas once in a while. There was some water in it and over the winter it froze in the float bowl where it squeezed the float. Since I put a kit and used float in that carb, I remove the plug on the bottom of the bowl and drain the gas every fall, and after each use in freezing weather. Machine is a 1958 model 75A "roadster" (no cab) with forks. Hawgfan in Arkansas
