JP Instruments EDM 700 / EGT Question
Trying to get my head around the EDM 700 by reading the manual and faffing around with it when flying. I notice the book says one of the diagnostic/troubleshooting features of this unit is if on take of you notice an exceptionally high EGT reading on one cylinder that would signify a gunked up plug. I would have thought that a fouled plug would have caused the EGT to be lower due to reduced or no spark and ignition and the unburned fuel having a cooling effect.
Anyone want to have a crack at explaining this?
