cranked up the sleds today and mgot new fuel in the carbs(has stable in it.) plus let the efi run. then i re fogged the motors. I was wonder what the fogging agent will do to the power valves?. we use this oil on the farm to loosen stuck motors, stabilize fuel, fogg out motors. I hade been wondering if sitting over the summer if this would loosen up the carbon on the valves, anyone have any ideas. also if it did loosen up the carbon could this be bad?
