I was flying my Nanchang CJ6 leading a 4 ship formation of Nanchang's and my troubles started with a mild RPM oscillations. So I went to full rich, scanned the gauges, which were normal and then turned the formation towards our home airport which was about 15 miles away. As soon as I had finished the turn the engine stumbled with a noticeable and significant momentary loss of power before picking up again. The engine gauges showed normal readings for the conditions and power setting.
What would you do ?
