Kohler KT30 - Single Cyl Roughness

I have a new to me RZT -S 46, 2016 model. I've always been a Kawi guy but this unit came up at a good deal. I'm trying to diagnose why the engine is running rough. Only one side runs rough. The other side is fine, thus ruling out fuel, air or carb issues. I have replaced the plug and have Amazon'd a new magneto. The problem seems to get slightly worse once the engine warms up. I do hear the occasional backfire, infrequent however. The unit only has 300 hours on it and is in very good shape. Power is low. The mower had a head gasket replaced before my time. The side that is rough also leaks a little at the valve cover. Any thoughts?

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
