So what do we think of this exhaust valve in a Continential O-200?
On the one hand, it looks like it has a good "burned pizza / centered target" sort of look. And I'm always looking for problems when none exist. On the other hand, the wide dark patch at the 2 o'clock position, and the two smaller, darker areas at the 7 and 8 (-ish) positions, looked different from the other exhaust valves.
Valve was not stuck, and spun freely in the guide (we did the "rope trick"). There was maybe (maybe) a little extra soot/carbon under the rocker cover.
