I have an 85 Piper Archer with the Lycoming 0-360-A4M and I only have a multipoint EGT. Since I can't measure CHT, I was wondering if having the mixture in the wrong position can cause CHTs to go over 400 degrees in cruise? I ask this question because with my carb airplane, I can't run lean of peak without the engine starting to run rough so I only lean to peak EGT. Sometimes I lean for peak RPM for what I think is best power on a given throttle position.
I met a pilot at Columbia County and he said he had a piper archer with an engine analyzer for many years and he said that the 0-360 carb runs cool in a cruise regardless of mixture setting so you don't have worry about having the mixture at the peak CHT position. He said that the highest CHT he had ever seen was 375 degrees in a hot day climb. I was happy to hear that.
Any 0-360 carb guys with engine analyzers seeing the same thing? What is the highest CHT you have seen in archer?
