Good call! I was hoping you would do just that. I have cleaned a couple of tanks with good outcome. But the tanks were much more expensive to replace than yours. Also carbking has a valid point in that the sealant can come off and you are back to square one, only now you also have to o/h the carb and replace the tank.

I didn't do it, no one saw me do it, you can't prove anything! "Bart Simpson"
