My EGT took a dump. I will use this as an excuse to replace it with a combo CHT/EGT. Current EGT probe is on the rearmost pass side exhaust stack.
Two questions:
Which cylinder should I place the CHT probe on (O-300 on a '47 C-170)?
Wag Aero has two metric sizes available, Which size do I order to place it in the small hole that was once used by the clock?
Thanks for your help.
