OK, when you adjust the valves, you have to remove the tensioner to remove the camshafts, so why doesn't the chain jump a tooth down on the crankshaft gear?
Is it confined (tight-fitting)?

The tensioner pushes against the long side of the cam chain. When you pull it off, it just introduces slack, but nothing will come off.

I dig that, but why doesn't it fall off the crankshaft gear? Since it's no longer taut.

It can if you pull on it. In the long run it doesn't matter because what you are worried about in the position of the cam not if the chain moves on the crank. When you put the cams back in follow the instructions for getting the cams in correct time.

OK
as long as you don't move the CS gear from TDC, and then line up the cam gears per the tutorial, you are OK?
I think I have it now. :)

What I do on OHC engines is to try to keep slight tension on the chain then
sort of hang it over the edge of the chain tunnel and hang a small weight on
it with a bit of bent wire may not make the slightest difference but makes me
feel better.
