If you're sure it's carbon fouling (not carbon/oil fouling), look back at you carb/air filter. Presence of carbon alone on plugs suggests unburned fuel. Sounds like your mixture's too rich. Check exhaust pipe. If pipe/plume is sooty, it helps to confirm rich mixture. If it was weak spark, you'd have missing and hard starting.
