No spark when cranking 128

[Steveshow]

I was going over the old 128 getting her ready to cut grass and she wouldn't start. I checked for spark and zero. I dove in and found the point block where the wire from the coil connects burnt up pretty bad. I had put new points in last spring when I used the tractor for the first time after inheriting it from my late uncle and ran it without issues. I believe the coil is not original and due to the damage to points, is not internally resisted (not marked either way) . In an effort to make a quick fix, i flipped the points insulator block over (less damage) and reinstalled the wire from the coil. It is not making a contact to ground now as best i can tell visually. I set the points at .020 gap. I also installed an external resistor that i had in the wire from the ignition switch (which goes to the positive terminal on the coil. I am now getting 13 volts at the coil and points. Still no spark at the plug when cranking so i checked the coil with an ohmeter and it was open. I checked another used coil i had as well as the coil off my running super c. Both had 5 ohms. I installed the used coil and the coil off the super c and neither will give spark at the plug. I ohmed the old plug wire and it reads 4 ohms. I tried a new plug wire from a set i bought for my pickup project as well. Still nothing. I ohmed this new wire and it read 1000 ohms. (???) i tried the old and new plug when checking for spark. I cant figure why the points dont spark when i open and close them manually. Still shorted out from the melted block i suppose. guess i will start throwing parts at it next week; new internally resisted coil, new points and new plug wire. Any suggestions?
