Hi All
Thanks for the comments. I'll try to answer all the questions.
Joe K - Here are some photos of the float valve and seat. The valve is steel or low grade stainless steel, it is magnetic. The threads on the seat are 3/8-27 UNS. The Zenith carb is 1/2-20 and the Tillotson is 7/16-24 so neither will work. I will try to find a replacement in the future.

Photo 2 - Closed height of valve from gasket surface 0.1850" or approx. 3/16"
Leo - I did have some problems removing the float valve seat and the main jet do to previous attempts at disassembly. I had to very carefully use an impact driver.
Jack - Is the carb you have similar to the one in this thread post #5?
