I read your foxy answer yesterday and I've been thinking about it ever since. I think there is a can of acetone in the garage. (There must be, because there is a can of everything else out there.) So I'm going out and try some of it in that gas tank. I'll let you know how it works out. On the other hand, if you see a mushroom cloud over Tennessee, I won't have to tell you.
