Yesterday after an uneventful Superior IO-360 startup and runup, while waiting to depart all of my CHT's jumped to around 430F while idling at 1000RPM.
As I barely see 400F on even the hardest of takeoffs this got my attention and I promptly shut the engine down.
Mixture was full rich and everything else was normal apart from an infrequent (2-3 times) "thud" from the engine and fluctuation RPM's before noticing the high CHT's.
While the plane remains stuck on the ground I am at a loss trying to figure out what could of caused all CHT's to jump up.
Let me know your thoughts
