I knowingly bought this 3 yr old 576 from original owner today with little or no compression.
Pulled the muffler and plug and saw very little scoring, but found the problem when I pulled the jug. It looks like something came in by a transfer and had a hard encounter with the piston.
If it was a crank bearing, wouldn't the crankcase be a little torn up? The pictures show how clean, and oily the crankcase is. The wrist pin and bearing are clean and full of oil too.
The throttle plate screws are intact and there was no evidence in the muffler of anything either. I know I'm the first to tear it apart because of all the saw cake on it.
What do you guys think?
