I'm still not sure how I would be able to mark the flywheel with out spliting the tractor. I can just barley get my hand in there, never mind be able to see what going on in there with my hand in there!
The only thing I could do is make a static mark some where on the front of my tractor and then make my own TDC & 30 deg mark on the crank pulley. That might not be quite so hard. Oh and I see you say 40 deg ATDC @ WOT, all my books say 30, maybe that's WOT under load?
I like the timing light with a tach idea, the only thing I worry about is if I do have slop in the drive system and I get the high idle zeroed in what that's going to do to my low idle timing. Using this method I'm assuming it's best to have the machine under load? I don't have a dyno but I do have some PTO implements that would at least give it a bit of a load.
Maybe I'm just being to picky. Can I really do terrible damage to an engine that WOT is 1400 RPM by being a bit off with the timing? Really, all I want to do is get rid of a miss.
I'm going to time it statically, see what that does for me, then go from there.

He'll be busy working and I’m handing him tools and he says, "give me that..." and I’ve already got it in his hand or "hand me that....."and I’ve got the portable light right where he needed it placed to see. "Run in the house and get me a...."as I open th
