If it were me having to get this bike going, I would be working at ruling out a fuel issue. Take the air filter out and crank the bike, shooting an aerosol like WD40 in the carburetor intake. If it fires, re-focus on the fuel delivery. If the song remains the same, go back to your electrical Exorcism. I'm not sure how you are checking for spark. Grounding fails as often as it works for me. An inline spark tester is only a few bucks and removes any question.
EDIT: Sorry. Sometimes I get distracted by things like the phone when putting together a post. You answered some of my questions between the time I began the post, and the time it actually got posted. Your skills at diagnostics may far exceed mine. I have little faith in the grounding method, and rely on an inline tester. About three bucks at an auto supply house.
