Sounds like those are just pieces of the thermostat that have come apart….
I would not worry about the rust on the cylinder walls…Clean the walls up with some light crocus cloth. The question is whether or not the rings are stuck….This engine does not have intake bypass covers making a visual inspection tough….Trying to remove the exhaust cover may open a can of worms if the screws are stuck and snap off….
I would point the pistons up toward the sky, then add whatever kind of soaking juice you prefer….Then try tapping with the wood block in a few days….
Once the pistons are freed up, then you can remove the powerhead and have a look at the exhaust hsg….I wouldn’t give up on this project quite yet, these engines are pretty tough and will continue to run nicely even with some imperfect conditions inside….
