Have changed condensor, points, distributor, plugs; cleaned fuel system; replaced battery. It will start by rolling it down a hill and dumping the clutch and then runs fine, but won't start by turning key and hitting starter button. The motor turns over but just won't start.
SOURCE: Ford 8N will not start when hot
If it cranks over it's not .....too hot.
Stops on it's own?.........sure sounds like a coil.
Put a cheap timing light on one of the wires....leave it on and drive it until it dies and watch the light for spark(light).
Or while cranking....hook the light on and check for spark.
You have to detect if there's spark or not.
Stick a old plug on one of the wires when cranking with a no start and check it.....we want the same spark as cold.
Does your 12 volt coil require a resistor to keep it from overheating? Maybe?
Throw one inline before the coil from a pre electronic ignition Dodge....that should take the edge off but still run great.
You may have to replace the points now if the resistor helps.....they may be burnt from high voltage......they don't like pure 12 volts.

The most likely cause of your problem is that the bendex drive on the starter is hanging up. This is caused by the return spring in the drive assembly breaking. First remove the battery cables then Pull the two bolts holding the starter to the block and remove the starter. It should drop out if it is difficult most likely bendex is still engaged just wiggle around until starter comes out.
NOTE: take caution as to not let end caps of starter come off. the bendex can be replaced by itself or you can purchase a starter with new drive bendex on it already.
to test if your push button is sticking take an ohm meter and test from terminal post to block or top of transmission where mounted if you get a reading of continuity then you have a bad starter button you can search for this part number 8N11500. The starter button just screws into the transmission cover and does have a gasket (pn 8N11529) and dust boot for the terminal. it is real easy to remove be sure area around is free of dirt you don't want that in your tranny.
No offence to HOGobal; putting a push button on the guage(aka dash plate ) is a bad ideal. The transmission mounted push button serves to keep the starter locked out if the tractor is in gear and yes the 2N,9N,8N,,NAA will start in gear and take off possiblely causing damage to your property,self and tractor. I have repaired to many push button remounts and have personally seen a 8n over come its park brake and run into another vehicle cause massive damage to the other vehicle. due to heavy duty push bar bumper assembly on tractor.

Clean all the connections where the solenoid bolts to the starter. They are copper. Make them shine.
