In the future,if you want to take the engine apart, leave the flywheel on the crankshaft and stick a zip tye or something softer than metal inside the exhaust port, then use your hands to spin the flywheel against the ziptie to allow your sleeve to come up so you can grab it. looking at the damage you have done to that sleeve, your better off starting over i would guess. That sleeve and piston looks ruined.
Good catch on the tool marks. Doubtful it’s ruined, but it sure doesn’t look pretty. Advice on hard liners to remove - USE HEAT and some solvent like acetone!! Soak the case in acetone for 10 minutes, drain, and heat up good and warm. The liner should slide right out. These engines’ liners’ have a slip fit. When clean and free of varnish, they should slide it easily.
