Starts, then wont restart

[Ramsey52]

We have an 8N with a front mount distributor that was running rough last year. It sat for the winter and became the summer/fall project. Started with a fuel change, new spark plugs and wires, new carburetor(the original was so rusted it wouldn't open), points, condenser, distributor cap, starter, starter button, some new wiring ( there was some original cloth wiring that was worn and grounding out), resistor. I realize that it is a long list of things that were replaced, but it seamed that as one issue was fixed another one took up the challenge.
At this point we can get it to turn over and start, it sounds great and runs smooth then when it is turned off it will not start again that day. This has been a family project and we are stumped. Any help that you could give would be so greatly appreciated.

As soon as the tractor stops running, not 5 minutes later, check for spark, fuel and battery voltage.

Does the tractor have a spark that will jump 1/4 in open air?*

Will the gas drain out of the carb bowl in a steady stream and fill a pint jar in less than 2 minutes?

What is the EXACT voltage at the battery? ( yes, you need a multimeter for that, not a worthless light)

How do I know this part is defective?

These are the questions you need answered before you attempt any repairs or buy a new part.

Once you figure out if you have a spark or fuel problem, post back and you will get plenty of help to fix the problem.

*If you dont own a spark checker w/ an adjustable gap ( NOT a light) buy one. In the meantime, an old spark plug w/ the gap opened to at least will work. Ground it to a
rust & paint free spot on the engine turn the key on & look for a spark.

Question: On the first day how long can you run it, can you work it as long as you want? After you shut it down and it sits overnight can you walk out and start it or do you have to do something to get it to start again?
