## Discrepancy

PILOT REPORTED WHILE TAXIING THE RIGHT HAND ENGINE HAD A HUNG START WHILE USING BATTERY POWER TO START THE ENGINE AND THAT THE ENGINE FAILED DURING THE TAXI, PILOT RETURNED TO HOME STATION. MAINTENANCE IS CURRENTLY TROUBLESHOOTING THE ISSUE BUT HAS FOUND THAT THE FUEL CONTROL UNIT IS THE REASON AND IS AWAITING POST ENGINE RUNS FOR OPERATIONAL CHECKS. REMOVED FUEL CONTROL TEST/TEARDOWN DISCLOSED CDP BELLOWS DISTORTED (STRETCHED) CAUSING LOW FUEL SCHEDULING.
