AIRCRAFT ENGINE HARD TO START AND RUNNING LEAN WITH HIGH TIT READING WHEN FLYING.  INSPECTED ENGINE AND FOUND CLAMP P/N 24609 (CONTINENTAL) WAS BROKEN THROUGH AND PRIMER VALVE WAS MOVING AROUND UNSUPPORTED.  THIS CAUSED THE PRIMER LINE TO WORK-HARDEN AND AT THE B-NUT CONNECTION.  SUBMITTER STATED THIS CAN CAUSE ENGINE FIRE AT A HOT START CONDITION.
