Re-breaking in my engine after prop-strike by hangar door induced by tornado.
Considering the engine already had 160+ hours on it - I know how it was running for a while.
I have one cylinder running not like the others. Before I tell what is happening, I want to make sure I understand/remember the basic concepts.
EGT-only elevated - CHT reduced...unburned fuel going out exhaust and burning on the way out - plug not firing
EGT-only elevated - ...unburned fuel going out exhaust and burning on the way out - plug not firing completely
CHT-only elevated...not enough cooling air
EGT and CHT elevated...lean mixture - air leak
Refresh my memory here.
