Default Re: leaking carb.

At one time the fix for a rusty tank liner was to mix up some permatex and alcohol as a gas tank coating. The alcohol, I believe, attacks this liner, and the fuel has a film that deposits on the float valve. The valve sticks if you leave fuel in the bowl, say from not running the motor after you shut off the gas. Marvel Mystery Oil in the fuel, or some diesel are possible additives. It is a PITA to remove the carb and free up the float valve.
