## Discrepancy

PRIMARY COIN HOLD DOWN RETAINERS LOOSE WITHIN MAGNETO CASE.  THE LOOSE RETAINERS, IN TURN, GOT CAUGHT IN THE TIMING WHEEL/GEAR AND CHEWED UP SEVERAL TEETH.  PROBABLE CAUSE-  THE RETAINERS WERE NOT INSTALLED PROPERLY.  FORTUNATELY THE DAMAGE WAS AT THE R20 TIMING MARK, WHERE WE WERE ABLE TO SEE THE DAMAGE DURING A 10 HOUR (ENGINE BREAK IN) VISUAL INSPECTION.
