Well the doggone flippin' piece of history wouldn't start after all of that.
Had spark, had gas, wouldn't fire even with ether.
I took the distributor off. The cap is labeled counter-clockwise 1-2-4-3 and the front cylinder is #1. There's no way to put the rotor on wrong but the distributor shaft is like a flat-head screwdriver going into a slot in the end of the camshaft and I had it off, .... just in case the engine was cranked over 180 degrees while I had the distributor off, I rotated the engine by hand with my thumb over the #4 spark plug hole and when I felt the compression stop and the suction begin, I knew it was at or near TDC between compression & power stroke so that's when #4 should get it's spark, .... and the rotor was pointed at the #4 terminal on the distributor so that's all correct.
So it's a total mystery.
But I have a theory.
Though it has spark, it may be too weak.
When I'm checking for spark, it's with the spark plug out, and resting on the head, looking at the 0.025" spark plug gap while I crank the starter.
It requires 22,000 volts to spark.
Typically the input voltage on a coil should be battery voltage with points open, half that when closed. This electronic ignition module is basically the same as points.
I get 12.42 volts at the top of the coil, then I cranked the engine by hand a little bit and it dropped to 1.8 volts.
This is with both the Ford resistor and the additional one for the 12 volt kit, using the old 1 ohm, 6 volt coil. One resistor feeding the other in series.
So I'll try bypassing one of those resistors or just put the 12 volt 3 ohm coil on it and wire it straight to the ignition switch.
It could have spark in open atmosphere but not when it's under compression.
A Jacob's ladder works on that principle.
It's two parallel rods, except they're slightly further apart at the top. A high voltage power supply makes the electricity arc between the two rods at the bottom where they're the closest, then the heat from the arc thins the air immediately above it. Electricity flows better in thinner air. So the arc climbs up the two rods until it reaches a point at the top where the gap is simply too much even with the heated air and it begins again at the bottom.
So it'll take more juice to create a spark in a pressurized environment like in the cylinders. No idea how many psi I get but it's enough to blow my thumb off the hole when I'm running the starter.
So Friday I think it'll be, when those terminals arrive I'm going to try bypassing one of those regulators with an alligator clip jumper wire and see if it'll run.
If not, ... the tractor is still safe because I still haven't found my sledge hammer.
