The rust in the tank will be a killer. You have to remove ALL of it or it will make it's way to the
tiny jets in the carburetors. After you've removed all of the loose rust that you can, treat the
inside of the tank with phosphoric acid. That stuff turns iron oxide (rust) into iron phosphate which
is a protective coating.
Good luck with your project!
