My '72 350 twin has, I think, water in the fuel. There is a white gunge all over the float bowl and carb parts. I even noticed some liquid beading on the floats. I think I used a gas container that was contaminated with water to refill the tank after rebuilding the carbs. My question is: How do I clean this up? I've cleaned the carbs again and removed the white stuff. What about the tank? Is there anything to do to get rid of the water? Thanks.
