I have a brand new Rotax 582 that I have been test flying. The PTO cylinder is running good temps (220 CHT / 1050 EGT). However, the mag cylinder is running a low CHT (190) with a high EGT (1150). This would seem to indicate incomplete combustion in this chamber. I have verified the carb sync several times now, tried swapping carbs, verified the torque on the head bolts and spark plugs, and even swapped sensors. Starting to run out of ideas now. It concerns me a little that the problematic cylinder is the side on which I installed the oil injection tank.
