Hello Guys. A question that arises from my last flight. I have an O-320 in front of a Mustang II and in cruise, I do mag check every 1/2 hr or so and before I start down. I realized that my EGT goes up 50deg F, along with the normal rpm drop, while on single mag. Is it normal? I only have EGT and CHT probes on 1 cylinder : #3 and #4 respectively. It almost looks like the mixture is getting leaner....
