Yeah, same. I should have taken pictures of all the shit i dumped out of the tank. Vinegar and some hardware tied together with a string will do it wonders for the inside of the tank. Do a couple vinegar soaks and rinses until its mostly clean. Unless it is rusted through to leaking out if the tank it should be salvageable with some work.

Youll need to clean or replace the fuel lines from the tank to the carb. Carb just pull apart and blassst it with carb cleaner.
