This is not what your engine should look like.

Well as some of you might have read in my other post last week when I was asking about cylinder type. I threw an exhaust valve while watching the fireworks on the 4th. Well I swapped out the damaged piston and cylinder for a serviceable one to get it back to my hangar.

This is what 2-3min of running with exhaust valve banging in the combustion chamber in a O-360 looks like. Thankfully the rings held up and piston didn't break to keep metal out of the case.
