carbs leaking water??

[His Dudeness]

Are you using water in your rad? If your using coolant it's usually green, blue or red so you expect the leak to be that colour if it's coming from the cooling system unless you're using water in the rad. Also when coolant dries it tends to leave a chalky white substance so if you're using coolant in the rad and there's no chalky substance then your leak isn't from the carb heater or any other part of the cooling system
