Depending on the engine, the cooling air duct may have to be modified in order for the CHT sensor to be mounted underneath the spark plug. Thats why its so important to manage the powerplant in a fashion that limits CHTs to a tolerable value. Whats important is the relative value of EGT for a particular cylinder compared to that cylinders peak EGT value. I didnt turn that fan on. Less fuel, more air creates a lean condition and be severe This is because un-vaporized fuel in some are even a bit over 500F. 275C.
