Just wanted to gauge an opinion on what y'all woulda done. This is a '69 Piper Cherokee 140. Great CAVU day. 16 deg with 2 deg dewpoint (Celsius). 30.31.
Oil level was good on preflight. Engine started as expected. Oil pressure looking good. Leaned for ground. Temperature coming up as normal. On the way to run up area, ground reported that they received a phone call from ground crew. They said my plane was making a knocking sound. During runup, oil pressure remained okay. No sound noted. Tried with carb heat hot and cold. Tried with both mags. Tried with mixture lean and rich. Still no sound. Oil pressure and now temperature looking great. On takeoff, oil pressure was pegged at the top of green, but no other abnormalities noted. On parking, nothing was of note under the cowling.
Would y'all have stopped the flight on report of what ground said? I could not sense a knocking or anything not unlike the aircraft's normal operation. My only suspicion was that because I was running lean for ground ops, the plane could have been knocking.
