"Wow, I'm sorry to hear that.
Make sure you ground the plug properly when testing as not having a ground could hurt the ignition. I use a piece of steel trolling line as a backup ground, just to make sure. Also make sure you have the throttle well past stop when checking as there is likely a ground to kill the motor when you set throttle to stop position.
Also, test in a dark place, and maybe cheat and narrow the plug gap. The reason I say this is that the electronic ignitions in these motors have been known to fail, and I'm hoping if you have any spark at all, the magneto is working. The problem is that Tecumseh no longer manufactures the replacement parts.
I don't want to jump to conclusions as it could be as simple as a bad connection somewhere, but since that motor has a solid state magneto, there isn't much adjustment to anything.
Check any wires you can to make sure they aren't frayed and grounding out on anything.
The service manual states you need a special tool to remove the flywheel on that motor. If you don't have a bad connection or wire, I would suggest looking at the magnets on the flywheel and magneto for issues.
I, fortunately for me, have not had ignition problems on my 7.5's, just my 9.9's.
Worst case scenario is you might be in need of a donor motor. I've had a few of these over the years, and even gave a good running 1975 away last year (to a friend). I have a 9.9 Eska that has gone through through ignitions over the years, and have been fortunate enough to find donor motors. I'm now at 20 years or so on the last ignition, so hopefully have a solid motor. If it dies again, I'll put the motor in the back of the shed and look for another donor motor.
I hope you find something obvious, but this may give you a good idea where to look."
