Bill,
I am not to familiar with the updraft carbs on the COE but we had them on old farmalls and it sounds like your float might be sticking and not shutting off the fuel flow. Happened a lot when they sat for a long time (like all winter) and the carburetor gummed up. Of course it could easily be something else, too.

I really enjoy looking at the pictures we took of your truck down in Waldorf. Maybe we can get together at a local show next spring.
