My Cub Cadet GT2550 (with only 126 hours of running time on it) is now running only on one cylinder. My son changed the Spark Plugs -- no improvement. He thinks that one spark plug wire may be bad, and needs to be replaced. Could the problem be anything else?

(Needless to say, the mower lacks power but can still mow 6"-high grass if one goes slowly).
