## Discrepancy

(CAN)  THE ACFT LOST POWER AND THE ENGINE STOPPED.  THE ACFT LANDED WITH OUT INCIDENT AND ROLLED OFF THE RUNWAY.  THE PILOT DID GET THE ENGINE RESTARTED BUT ON FOR A FEW MINUTES.  DURING A INSPECTION OF THE ENGINE THE MIXTURE ADJUSTMENT SCREW WAS FOUND MISSING. THE ACFT HAD BEEN RELEASED FROM MAINTENANCE THAT DAY AFTER AN INSPECTION 1 WAS CARRIED OUT.  THE ADJUSTMENT SCREW WAS INSPECTED AND ADJUSTED. TORQUE SEAL WAS APPLIED FOR A ADDITIONAL SAFETY.   THE ADJUSTMENT MAY HAVE BEEN BACKED OUT TO MUCH NOT ALLOWING FOR THE SPRING ON THE SCREW TO HOLD IT IN PLACE. THIS WAS SUSPECTED.
