## Discrepancy

REMOVED SPARK PLUGS FOR O/H AND REINSTALLED IN AUGUST 2012 AFTER O/H.  RAN UP ENGINE FOR OIL CHANGE, NOTICED THE ENGINE WAS MISSING ON THE RT MAG DURING MAG CHECKED.  REMOVED PLUGS TO CLEAN AND GAPPED AND FOUND NR 3 CYLINDER BOTTOM SPARK PLUG INSULATOR BROKEN.  BORESCOPED ENGINE FOR ANY DEFECTS AND NO DEFECTS NOTED AT THIS TIME.
