## Discrepancy

THIS FUEL VALVE DID NOT MEET THE CRITERIA OF MFG  S.B..  THE RUNNING TORQUE OF THE VALVE WAS VERY HARD TO MOVE.  WHEN TESTED WITH A TORQUE WRENCH IT EXCEEDED 25 INCH POUNDS.  THE FUEL VALVE WAS DISASSEMBLED FOR LUBRICATION AND VALVE CONE WAS FOUND TO BE SEVERELY SCORED.  THE VALVE WAS REPLACED WITH A NEW FUEL VALVE KIT NR 2390151S.
