Well my son drove over my saw the other night
The saw was in otherwise excellent condition with pretty low hours, replacement cost over $400.
I picked up a new plastic case for $40, new throttle handle $40, new rings $50-25 a piece Stihl part# (1127 034 3002), new flywheel $20 Stihl part #(11274991200).
The satisfaction of rebuilding it with no labor costs priceless

Take your time putting the rings into the cylinder they break easily, which was the only reason I had to replace rings. I used a set of plastic chop sticks and a nice wife to hold the rod while I set it in place
Like everyone says "no" you can't hold the flywheel with a screwdriver to tighten it. I broke a fin off which is why I replaced it.
Thanks to D'Animal for your posts on disassembly.
