52 8N no fire

I"ve replaced the points, condenser, cap, coil, plugs, plug wires, ballist resister, and key switch. It"s a side mount with the 12v conversion. It still won"t spark at the points or plugs, and the resistor gets a little hot and smokey but it only done it when I first put it on. Any tips because I"m ready to stick dynamite in the tail pipe push it down a hill.

How do you have your 12V conversion wired to the coil?
Round can 12V coil marked "No external resistor required" or similar?
If so, you shouldn't need a ballast resistor.
If you have a 6V coil, or a coil marked for use with an external
resistor then you do need a resistor, but the size will need
to be matched to the resistance of the coil your using.
Do you have battery voltage to the coil with the points open, key on?
That would be a good starting point at least.
As said, lots of help on the YT N forum too.

Well, you certainly gave it enough parts. Did you actually do any diagnosis? Or just throw parts at it?
Start here......
Check that the coil is getting voltage at the hot side. That is the side AWAY from the distributor (electrically).
If you have voltage there, check the continuity of the points when they are closed. Then check to see if they will make a test light blink as the engine is turned over.
There is a possibility that even a NEW condenser can be bad or shorted. Check it with an ohm meter. Should show an open circuit. If you have an analog meter, it should initially show a pulse on the highest ohms scale, and go back to open circuit.
Next, check to see that everything is installed CORRECTLY - points gap, wires not pinched or shorted, terminals not bent and touching distributor housing, and other things like that.

If all else fails, make sure your insurance is paid up before you do the dynamite. {{grin}}

Just because the parts are new does not necessarily mean that they are good parts. I have had new condensers that were bad, new points that were bad and new switches that were bad. Fortunately not all on the same tractor or "job". Check the condenser "out of the circuit". Check the points (disconnect the wire and check the points to be sure that they are making contact and opening to "open circuit"). Check the coil (independently) by checking the resistance across the terminals and by applying power across the terminals and checking for spark. Then check the wiring to be sure that it is correct.
The "side mount" distributor is the MOST DESIRABLE and the much easier to work on than the "front mount" distributor. You are fortunate to have a "side mount" distributor.
