Fue; additives actually do work to clean gunk from the fuel system. I've used several different ones including everybody's favorite, Marvel Mystery Oil.
I'd use a can of carb/choke cleaner and heavily spray every orifice on the carb. Spray down the throat, etc.
A few years ago I researched fuel system cleaners in order to revive my brother's motorcycle which had been sitting for years.
The primary chemical used to break down varnish and crud in fuel systems is a name I can't remember. Suffice to say that it works and the products that have it in the greatest concentration are;
Redline, Techron , and Lucas
I've used Redline with good results running it at a higher concentration than the bottle says when starting up a a Mustang that sat for 15 years.
Lucas Oil: LUC10013
Red Line: 60103
