My cylinder and cylinder head is really really, I mean really dirty with rust and red clay. I'm going to replace the 4 bolts, the head gasket and the cylinder base gasket. Removing the cylinder head seems easy enough. When I remove the cylinder, for what should I watch out? Will the piston rings break? And when I put the cylinder back in, I know to put some 2-stroke oil on the piston, should I also coat the walls of the cylinder? Watch agent should I use to clean this rust and clay off? After I clean it, I hope to spray paint it. I've got some high heat flat black spray can that I hope to use. But I might want to spray the cylinder head chrome. How hot do normal engines usually run so I can make sure the chrome doesn't start to peel or turn into fire. Thanks for your help.
