Cleared for Takeoff
Yesterday my C-172 partner sent me this pic of the engine monitor after a 2.5 hour flight home, WOTLOP 2400 rpm at 6500, IO-360 with matched GAMI-jectors and FP prop.
Two possibilities immediately come to mind - leaking/stuck exhaust valve on #3, and possibly a clogged injector on #3. Since this was WOTLOP if that cylinder went any leaner, this is what I would expect to see. Any other suggestions?
I'm going to do a compression test this afternoon, if that looks good then I'll take it up for a very close lean-test to check peak on each cylinder against fuel-flow spread. Hopefully one or the other will give me a clue.
