Last winter I was doing some solo work in the our practice area when the engine flamed out after a power-off stall. It turns out the little C-150 didn't like the rush of -20f air after turning the carb heat off and adding power. The engine re-started no problem and ran fine the rest of the flight, but I will stick to less drastic maneuvers when it is so cold. At the time this happened I had about 10 hours at the controls so the emergency procedures were very fresh in my mind and went smoothly.
