Thanks Old and Soundguy. I did try all you said except for the hand off and on the air intake while running. i'll check with O'rieley's and napa for a kit and give it a try. They sell the new Zenith if the rebuild goes afoul. All my auto carb rebuilds went to the scrap pile and bought a new or rebuilt carb but this TSX-580 doesn't look too complicated providing the internals aren't all pitted up where new parts go.

The tractor carbs are very simple and so simple that people make them hard. You do need a bucket of carb cleaner to soak the carb in for 24 hours or so compressed air to blow it out a couple cans of spray carb cleaner and a small wire or what I use it a torch tip cleaner tool to poke into the passage ways to make sure all are open as the need to be. The Walker kits have good instruction and a picture of all the parts

Basic carb rebuild kit from YT seemed to do the trick.Soaked the disassembled carb in pine-sol for 4 days then hot water bath, blow dry and reassembled.New fuel line and shut-off and new 1 wire alternator to finish up the 12v conversion. Going to tackle the PTO seal now so i don"t have to keep a drip pan under the Diffy. None of the parts stores in my area of SW Mo. had a kit that said it was for a TSX-580 carb. It showed for 4 or 5 TSX models but not the 580.
