Hey, Guys. Sorry it took me a week to get back at it. Thanks for all the helpful suggestions, so far. All useful stuff to know whether it winds up being the fix or not.
With the fuel turned on, the carburetor is dripping fuel from the little screw at the very bottom. Not on purpose. I hadn't loosened any thing. When I tighten the screw, it still drips. The fuel may be coming from somewhere else, and this just happens to be the low spot that it drips off. There is a "wet look" that extends part way up the carburetor with the high spot being the choke. Is it possible to have some sort of capillary action where the fuel is traveling up through the grime, or is it likely leaking from the highest point that looks wet?
Another thing I noticed was that when I loosened the screw, it only comes out so far--you can't take it all the way out. Is that how it's supposed to be? It screws into what looks like a little red nut or bolt head at the bottom of the carburetor. This nut/bolt head looking guy has some sort of sealer between it and the rest of the carburetor. Is it cool to unscrew this guy? It may be where the leak is coming from.

Although he himself has never actually owned or restored a tractor, he was always enthusiastic and always around helping with other peoples projects.
