Ok NO SPARK on my Tea 20

Before anyone suggests looking at Bla bla I did, I bought a new Coil, new Distributor, I hooked the ignition switch wires together, I ohmed out the coil wire, I check all connecting wire this tractor is 12volt, has no resistor to be bad..... Whats next?

1. Make sure distributor is turning.
2. Pull coil wire out of Distributor and crank with wire held near a ground. If no spark there it HAS to be in the points/ coil/ power area.
3. One thing to check is if the points are grounded accidentally anywhere- like where the wire goes through the housing, or even the points themselves could be defect.

Did you replace the points ? If you did try filing the faces a little , they are sometimes covered in clear lacquer to stop corrosion , it also stops the spark .

Sounds like the bla bla is what's wrong.
You checked the ohms? So you got a multi meter. Sit on a box with the black lead on the battery terminal. Just track down every end of every wire.... 3 or 4 at max?
Another thing, a couple years ago there were NO new condensers that worked at all. People were hunting down ones from the 90's or earlier...

Ok I went through doing both to all the wires IE ohms and voltage tests. A thought, could the coil have been cooked? The system was in place when I bought the tractor and there is no Ballast Resistor on the tractor......should there be?, I ran the tractor like this for about a year now but I did notice the coil got HOT to the touch.... If I buy a new coil and resistor and add the resistor what is the worth thing that could happen?

Look at the label on the coil and it should say if a resister is needed or not. It's not unusual for someone to think resisters aren't needed in this day and age and not put them in. The coil will work for a while until it does fry itself, assuming it's the kind that needs a resister. If you have power into the coil and the points are correctly adjusted and you have good ground then its quite possible it's toast.
