And if you're REALLY (un)lucky (like I was), you might hear air rushing
past a stuck exhaust valve and hear the hiss out the exhaust pipe when
pulling it through. Then you'd have it narrowed down to 2 cylinders...

good thought. Another I heard is to pull prop thru all 4 cylinders and feel
for "flat" cylinder.

Am I chasing nothing or what is a valid approach?

Thanks, Dick


get someone else to start your aircraft and stand beside him
listening. obviously he thinks he can hear something.
probably a clack clack clack sound which quickly vanishes as the valve
frees up and goes back to tolerances with the rocker.

just a thought.
