This sounds to me like it is somehow losing power to the points while cranking. Something like a bad ignition switch? A shorting starter switch? I night suggest that you try running a jumper wire from the battery to the hot side of the coil and try it then. If you have negative ground, run the wire from the battery positive to the coil positive. If positive ground, from the negative battery terminal to the coil negative terminal. Some things that come to mind: 1) If the ignition switch is the same switch as the starter switch, like on a car, the switch could be breaking contact to the ignition system while cranking. 2) If there is a bypass for the coil resistor, it might be an open circuit - as in having a break in the wire someplace. 3) If it has an automotive type solenoid on the starter, and has TWO small wires going to it, one is the start trigger wire and the other is to bypass the coil resistor. Could be a bad solenoid.
Not a terribly complicated system. Limited number of things that even can go wrong.

Jon's Allis has a small front loader and though it doesn't carry much, it serves his needs. It was the hard starting and low power that made him think it was time to replace the old girl. Jon called me to help him discover why his tractor wouldn't start
