Not sure I can identify a rapid falloff in turning resistance (books definition). I think you can. It should be pretty straight forward. As you rotate the prop you can feel the resistance from each cylinder on the compression stroke. If you hit a cyl. with a stuck valve, you'll notice the difference in resistance right away. If it's quiet, you should also hear hissing at the exhaust pipe if it's an exhaust valve. John Galban=====N4BQ (PA28-180)
