## Discrepancy

DURING OPERATIONS FOR WEIGHT & BAL PURPOSES, FUEL VALVE TURNED TO 'OFF'.  AS VALVE WAS BEING TURNED BACK TO 'ON', IT BECAME STUCK IN INTERMEDIATE POS.  LINKAGE BTWN COCKPIT & VALVE CHKD & FND IN PROPER ORDER.  AFTER 2 OR 3 ATTEMPTS, VALVE RETND TO 'ON'.  WHILE PERFORMING A COLD FUEL TEST, VALVE AGAIN BECAME STUCK & COULD NOT BE RETND TO OPEN.  AFTER SEVERAL ATTEMPTS, VALVE WAS RETND TO OPEN.  FUEL BOOST PUMP TURNED ON BUT COULD NOT GET FUEL TO ENG LINE.  VALVE REMVD & COVER PLATE REMVD FROM VALVE.  CAM THAT POSITIONS INTERNAL PLUNGERS BROKEN & JAMMED IN OUTLET PORT.  PLUNGERS BEING SPRING LOADED TO CLOSED POS WERE PREVENTING FUEL TO FLOW TO ENG.  HAD MALFUNCTION OCCURRED DURING FLIGHT, ENG WOULD HAVE QUIT.
