If you're fouling plugs your jetting is wrong. The mixture is too rich to allow the plug to reach and sustain the minimum temperature required to allow it to be 'self cleaning'. Your suffering from reliability problems as well as a loss in performance due to incorrect jetting. Fix the carb. Hope This Helps.
Check your premix ratio, carb jetting and make sure you are running the right spark plug.
