## Discrepancy

AFTER RETURNING FROM A FLIGHT, THE CREW REPORTED THAT THE ENGINE WOULD NOT IDLE BELOW 1000 RPM, AND WAS ROUGH AT INTERMEDIATE SPEEDS.  IDLE MIXTURE ADJUSTMENT HAD NO EFFECT.  THE CARBURETOR WAS REPLACED AND THE AIRCRAFT WAS RETURNED TO SERVICE.  UNIT WAS OVERHAULED BY L.A. AERO ENGINES.
