Get it running before you consider converting it to 12 volts. I have 7 front mount Ns. I have never had a coil go bad (but it is possible). Put a test light on the wire to the top of the coil and observe while trying to start the engine. Light should go on and off as the points open and close. If not, the the problem is inside the distributor. Most likely the points are not opening and closing (or making good contact). Time to remove the distributor and adjust, clean, or change the points.

I assume the other end of the test light goes to the (-) on the battery.
I'll do this tomorrow. On a side note I'll have to get some new 8-32 x 3/16 screws for inside the distributor. I have very little time running it since I changed points and I seem to recall that while setting the points ... the maximum I could set them was what is called for and no more.

You assume wrong.The clip has to go to the tractor ground, positive terminal of battery.You better forget the 12 volt bit.The adjusting screw is actually a rivet.You need a lock washer on the screw that holds the point setting.
