## Discrepancy

THE PILOT REPORTED A ROUGH ENGINE IN FLIGHT AND RETURNED TO AIRPORT,  A SAFE LANDING WAS MADE.  MAINTENANCE GROUND RUN AIRCRAFT AND A FLUCTUATION IN FUEL FLOW WAS NOTED.  THEY FOUND THAT THE MIXTURE CONTROL WAS STIFF WHEN MOVING. (POSSIBLE GALLING).  FUEL CONTROL WAS REMOVED AND A NEW ONE INSTALLED,  ENGINE WAS TRIMMED, TEST FLIGHT CHECKED NORMAL.   FUEL CONTROL WAS SENT IN FOR WARRANTY.
