First post, here I go.

How in the :evil do I get the magneto off. I have been at this forever now! Thanks, Cooper.

OK, finally got it using a puller, stripping the threads on the crank, and using a 5LB mallet.

Next off, chain tensioner, are these in the head?

I hated working on those things I always got shocked bad my hair would stand up. Look like a cartoon, I did HAH....
