Couldn't I just pressurize cylinder with compressed air and get same result?
If you use compressed air, make sure it's in gear so the air can't accidently rotate the engine.
I've had that happen.
Also, have the piston on it's highest point when doing this just in case you do loose your air.
If that happens, the piston will catch the valve and keep it from falling right inside the bore.
