## Discrepancy

AIRCRAFT LANDED AFTER CROSS-COUNTRY.  WHEN THE PILOT ATTEMPTED TO DEPART, ENGINE WOULD NOT START.  TROUBLESHOOTING DETERMINED THE POINTS IN THE LEFT MAGNETO WOULD NOT CLOSE COMPLETELY.  GAP WAS WITHIN TOLERANCE.  RETURN SPRING APPEARED TO BE BOWED, NOT SUPPLYING ENOUGH TENSION.  INSTALLED NEW CONTACT KIT.
