A bit of diagnostic work showed a left mag circuit failure. An engineer this morning found it was a failed plug on that circuit.

..A fouled spark plug is a common occurence in the older, carburated piston engines..For this reason,
understanding the mechanics of the ignition system is a must..A misfire condition at low altitude, especially after
takeoff, can bring a single-engine plane down, if no action taken by the pilot..
