[A5555]

After 5 flights with this condition it was enough to make me pull the top cowl to have a look. there it was, bugs, and others wedged in between. a check flight today with 35C OAT. CHTs are normal again, all within 10F. I cannot believe how sensitive the CHT is for airflow around #3 and why bugs only collected at #3.

Had a small part of my cowl seal folded back after an oil change. #3 shot up so fast I turned back and landed.

You're right, sensitivity is through the roof ... #3 is my problem child too.
