It's a 1967...E2755568. I was going through the carb..things look good/clean. I shot carb spray and canned air through all orifices and passageways. It has a cork float. Assuming it's still good(???),should it get a coating of dope or similar to use it with ethanol gas. I don't know when this o/b last ran. It fired on fuel shot into the throat for a few seconds.
