## Discrepancy

ACFT OWNER STATED; PROP DOES NOT WORK CORRECTLY AND WITH ENGINE OVERSPEED, PROP AND GOVERNOR INSTALLED NEW 1-15-98.  BENCH CHECK GOVERNOR, FOUND ONLY 80 LBS PRESSURE, NEEDS 290.  REMOVE RELIEF VALVE AND FOUND THE VALVE SEAT PN A-20572 SMASHED AND IN 3 PIECES. GOVERNOR BODY DAMAGED AS WELL DUE TO THE SPRING SEAT BEING HAMMERED BY THE RELIEF VALVE.
