First off thanks for letting me join.i have a 25 hp Kohler Magnum that runs fine as long as there isn't a load on it. Soon as you engage the blade and mow maybe 10 ft. it start losing power to the point of dying. You can quit moving and it will catch back up both spark plugs are firing at all throttle position. Oh sometimes it backfires thru the carb......HELP
