## Discrepancy

OPERATOR REPORTED DIFFICULTY STARTING THE AIRCRAFT. UPON CHECKING THE MAGNETO TO ENGINE TIMING, IT WAS FOUND THAT THE RETARD BREAKER POINTS WERE OPENING VERY LATE. REMOVED MAGNETO, DISASSEMBLED AND INSPECTED. THE CAM FOR POINTS WAS FOUND TO BE SEVERELY WORN. MAGNETO WAS REPLACED AND OPERATIONS WERE SATISFACTORY. IT SHOULD BE NOTED THAT THE CHAMPION / SLICK FOR THE 6300 SERIES MAG CALLS OUT FOR A 500 HOUR INSPECTION. THIS MAGNETO HAD NOT BEEN REMOVED FROM ENGINE SINCE NEW AND WAS 100 HOURS PAST RECOMMENDED TIME.
