Oh Andy, you do realize I am a dumb ass. But I will check all of that stuff to the best of my ability. I don't have the book yet, and I may come back and ask a bunch of silly questions. Thanks for looking out for me!!

Inspect the top (small end) of the rod, needle bearing and wrist pin. Shouldn't be any scoring, esp in the rod bushing. A little discoloration of the wrist pin is normal, but if it's blued from over heating, you'll need to dig worry about the rod too.

Push the crank to the bottom of it's stroke. Grab the rod and hold it upright.()
You should not feel and up and down movement, and no side to side. A little wobble is normal.

Repeat at 90 degrees all around to check further. If there's any play though, at the bottom of the stroke is were it's usually at it's worst.

I'd grab the flywheel and check for play in the mains there, no wobble and no in 'n' out.

If you really want to go all out, pull the clutch cover and check that side too.
