I need some assistance from the VAF braintrust regarding an issue on my IO540 powered RV-10
I just finished my phase one and wanted to take my son flying. After completing the 40 hours I landed, turned the airplane around and did my first hot start in the plane. First thing I noticed was low fuel pressure and assumed it was due to vaporization. Running the fuel pump on the ground seemed to fix that. A few of the cylinders got hot during taxi, 420 CHT or so but nothing too high. They came back down with a fast taxi.
Once airborne I noticed both CHT and EGT on cylinder #2 stayed way high. EGT was in the 140-14200 range, a good 200 degrees above any other cylinder. The CHT was in the 405-410 range, again well above others. It leveled there and did not move a lot and di not continue to climb. I cut the flight short. In the pattern and at taxi back (low power settings) the temperatures were back in line with others.
Yesterday I figured I would take a trip or two around the pattern and see what the temps did. All normal on taxi out and run up. As soon as I applied full power #2 spiked again and again leveled around 1400 degrees EGT. I finished the lap in the pattern and shut it down. A few hours later all temps in all cylinders measured the same at ambient.
I assume it is not a sensor as both EGT and CHT's were high for that cylinder.
Did I damage a plug, burn a valve or?
Your thoughts are much appreciated
Thanks
