Oh I wouldn't keep this one a secret for anything. It's a classic never assume troubleshooting lesson if there ever was one.
After reinstalling the distributor and again seeing the spark when I let go of the key I knew I was being told something but what it was I could not be sure. I spent a fair amount of time verifying the wiring without coming up with anything new. I hit the net and searched on my symptom and came up with some auto boards with posts that were the same thing. Spark when they stopped cranking. There were some plausible suggestions regarding the starter solenoid and the fact that the act of starting was drawing down the voltage to a degree that the coil could not muster up enough oomph to fire a spark.
That made me realize I had pretty much cleaned every terminal but the ones on the ignition switch. OK so maybe I have a bad connection there and I go out and pull the switch to clean all those terminals.
And that's when I see it plain as day. Never assume that the last person who owned your tractor knew what they were doing when they messed around with it.
The hot wire to the coil from the ignition switch was wired to the accessory terminal of the switch. So when I turned the key on it would indeed send the 6V to the coil. But when I checked the switch with the multimeter turning the key all the way over to run the starter causes the switch to cut off the 6V to the acc terminal while cranking. No 6V to the coil while trying to start means I don't have any spark.
All I had to do was move the wire from the ACC terminal to the IGN terminal on the ignition switch and my spark plug clamped to ground fires every time the rotor comes around. :D

Today's Featured Article - The Cletrac General GG and the BF Avery A - A Bit of History - by Mike Ballash. This article is a summary of what I have gathered up from various sources on the Gletrac General GG and the B. F. Avery model A tractors. I am quite sure that most of it is accurate. The General GG was made by the Cleveland Tractor Company (Cletrac) of Cleveland, Ohio. Originally the company was called the Cleveland Motor Plow Company which began in 1912, then the Cleveland Tractor Company (1917) and finally Cletrac.
