5200 update
Well the install of the new Piston etc went ok and the cylindr looked good but when i satrted turning the engine over by hand i heard some friction. i took the cylinder back off and there was one little spot of chrome flaking on the cylinder, she already started to mark up the piston so i will be looking for another 5200 cylinder. it is a complete saw with 20 bar and newer chain. oh well i will hold on to it until i find a usable cylinder.View attachment 295021
well getting it apart is done now and i used a few lubricants and heat to get it done, The rings are frozen, more like welded into the piston, i am thinking heat is what caused the meltdown. The cylinder looks good and feels even better. i used PB Blaster and MMO and one other brand but the heat is what got it to move finally, anyway i will let you guys know how it turns out, thanks for the help yet agian.
