## Discrepancy

ENGINE WAS RUNNING ROUGH AND DIED IN CHOCKS.  FUEL WAS SEEN POURING FROM CARBURETOR/AIRBOX.  CARBURETOR PN AV10-4164-1 (SN AV17142109) WAS REMOVED AND DISASSEMBLED FOR INSPECTION.  FLOAT HAD FILLED WITH FUEL, BOTH HALVES, AND 3 PINHOLES WERE NOTED IN WELD AREAS.  SAME DISCREPANCY WAS NOTED LAST YEAR ON SIMILAR PART NUMBER CARBURETOR (DIFFERENT SERIAL NUMBER/REGISTRATION NUMBER).  CORRECTIVE ACTION LAST YEAR WAS FLOAT REPLACEMENT.
