It sounds as if you have the Choke-A-Matic option. I recall Scott Bonnar fitted it on some SB45s.

If there aren't any air leaks and the choke doesn't make any difference, I'm afraid the carburetor will have to come off again for cleaning. I'm happy to lead you through the process using the Briggs technical manual.
