## Discrepancy

COIL TAB WAS BENT TOO FAR UP DURING MANUFACTURING INSTALLATION, WHICH CAUSED A DEEP ANGULAR DIVOT TO BE WORN IN THE COIL TAB BY THE DISTRIBUTOR BLOCK GEAR SINCE IT WAS NOT FLAT AGAINST THE GEAR. MAGNETO HAD NOT BEEN OPENED SINCE NEW AND THIS DAMAGE WAS DISCOVERED AT THE 500HR HOUR INTERNAL MAGNETO INSPECTION.
