An old dirt bike trick is to insert a piece of rope down the spark plug
hole. This jams the piston from moving when you wrench on the sprocket.
I'm sure this is not best practice or recommended in the manual but it has
worked for me on numerous engines.

Well, I finally got around to digging into the old engine (you remember
that one.....the "'gunk" engine...) Got the head off, then got the
cylinders off. Here's the surprise: the rod bearing on #4 is bad. Yeah,
you read that right, #4. I thought it was supposed to be #3?? I can grab
hold of the piston rod and just wiggle it around. So, for all you doubters
and naysayers....yep it was a rod bearing. Now I have to figure out how to
get the front sprocket off so I can get the cases split. The dang thing's
in neutral too. Any ideas?
Also, anybody in need of a head or cylinders? So you know, I've already
sold the cams.
