Hello,
Now 43 hours from new - last flight the CHT on Cylinder 2 of my Lycoming 390 performed erratically whilst the other 3 CHT were as normal at around 340 Fahrenheit (170 degrees C). Number 2 cylinder moved very quickly between 340 and 410 Fahrenheit (170 and 210 degrees C) and then returning back to normal.
I tried various settings flying LOP and full rich but the erratic CHT on cylinder 2 continued.
Any suggestions of the cause would be most welcome.
John
