We've had the carb apart half a dozen times now. It's got to be a sticking float or needle, but everything works PERFECTLY when the carb is apart. There are no scrape marks on the float from hitting the bowl, and the pivot is clean and smooth.
It's probably the %$#@ rubber-tipped needle, but we've got no choice in the matter. You can't get anything else and the original needle won't seal anymore.
We tried the seating trick, by putting the needle in the seat and tapping it with a hammer. That left an imprint on the needle tip, and we thought we had the problem licked. Tractor started right up next day and ran for 20 minutes straight. Then it sat for a few weeks. Problem's back.
Time for a new needle and seat. This time, take a can of spray carb cleaner and thoroughly drench both the needle, and then the seat, and then blow them dry with compressed air.
I have found that there is a residue on those parts, left over from the manufacturing process, and when it comes in contact with gasoline, becomes very sticky. You'd think the gasoline would eventually wash it off, but it doesn't seem to.
For what it's worth, I've never had any luck with seating trick. It only destroys the rubber tipped needle.

He got this wild idea that we should get a convoy of AC tractors and drive them from Charlotte, Michigan 105 miles to LaGrange, Indiana.
