Can anyone tell me the float height on a Zenith carburetor on an AC C?

Level when you turn it upside down.

I just set mine @ 3/8” and opened main jet up (2) drill sizes on a CA a few weeks ago and it seems to be working well. I have not had a chance to pull hard for long durations yet.

You might find once you put that Tractor under load, the ole' girl might start pushing black smoke. May be a bit on the rich side....

I will not really know until I plow the garden in the fall. So far she has been pulling a 8’ drag in the horse arena in 3rd for about 20 min each time and said it’s running stronger than before. Was running lean on fuel before I worked on it. I am questioning the float setting now as I think the book requires 5/16” without it in front of me?
