Ok, I finally have a minute to report.
On my spare CDI, from case to stud, on the 2Meg setting, no continuity at all... Either direction.
For some reason, I have very low (like 5 ohms) between the spark plug wire and the case, both directions.

Hope that helps somehow.

UPDATE:

 

I ordered Dale's TCDI unit and installed it today. I followed the directions to a T. I hand turned the flywheel per the directions and got nothing for a spark. So I backed up a bit and tested the stator. Cranked the engine and I got 22VAC as a peak and a steady 10VAC on the meter. In the directions Dale is saying it should be a steady 55VAC. I'm guessing the stator is bad?? Possibly the problem all along?

Which wire(s) are you testing? The single wire that attaches to the new module is your feed wire. It should check at between 115-150 or so ohms on resistance. It could be that, but it's not common they go out unless mechanical damage. If you think it's a problem, you can try to find a used one or contact Ed, I think he has a setup and can test it for you to make sure.

I just talked to Dale and he thinks its the stator.

Update:

 

I hooked up Dale Colvert's TCDI unit on Wednesday night. After having Dale rework my stator. The first video is the result. Dale could not have been more helpful. I had problems along the way and Dale guided me through them. I had it running for about 5-10 minutes no problems.

 

Last night I began putting everthing back together. Started it. No problems!

 

Tonight I put a new choke cable in, put the hood/shroud back on, and gased it up. So because it had been sitting for a couple months I gave it a quick bath while running. No problems. Got on it to drive around the yard and throttled up and all of a sudden it stopped. Like it hit a brick wall. The second video is what now happens when I turn the ignition. Note: everytime you hear it click I'm turning the key to start. The third video is me moving the flywheel with the starter not engaged and the spark plug out. I should be able to move the flywheel around no problem as I did when I installed the TCDI unit.

 

Any ideas?

 

Mike

Hmmmmmm? First video I heard a knock coming from the engine. After seeing the 2nd and 3rd video, I am thinking either the rod cap broke off or something happened to a valve, Like the keeper came off one of  them or you have a valve that is stuck?

 

At minimum I would pull the head to see what is going on in there. Good luck! I'll be hoping for something simple like a stuck valve!

I just watched the 3rd again. I hope I am wrong but it does have that distinct sound of the Crank hitting a rod that broke off. I am still hoping for a simple fix for you though!!!

Well I bought this tractor a year ago and honestly it has had that knock since then. Tomorrow she'll come apart.

Tecumseh engines are known to have rod issues. It is usually attributed to the oil not being changed when needed and not keeping the oil full at all times. And it is always hard to say how it was treated by a PO. When a Tecumseh is taken care of (as it should) they will last forever. Again good luck!
