Ya know ya keep dancing around it but what you need to do is. 1. take the carb off and clean it 2, take the clutch apart and figure out what the hell is going on in there. Chances are the plates are just stuck together. pry them apart, sand the steel plates a bit and put it back together. 3. take the clutch cable off and lube the hell out of it if it can even be brought back to life. I would suggest taking the entire cable off and soaking it overnight in brake fluid to try and knock the crap loose inside the housing. Do those 3 things and youll have a whole lot better idea what is going on inside there. If you cant figure out how to work on the clutch just post up some pictures of what your puzzled about. Somone on here will know how to get you thru it. But untill you get that side cover off you wont know what is in there.
