What was found
(CAN) IF THE ACFT WAS PARKED OUTSIDE IN COLD WEATHER (BELOW 0°C) THE FUEL WOULD NOT FLOW FOR PRIMING WHEN THE BOOST PUMP WAS ACTIVATED. CONSULTATION IDENTIFIED A SB (SIL-RS-84) ADDRESSING THE PROBLEM OF COLD STARTS DUE TO INADEQUATE CLEARANCES WITHIN THE VALVE CAUSING STICKING OF THE PISTON WHEN THE METAL CONTRACTS IN THE COLD. ONCE THE ENGINE OR VALVE IS PREHEATED AND STARTED, OPERATION IS NORMAL. VALVE WAS REPLACED.
