Firts up I would say the carby is toast looks like ethanol has been in there and you won't get the main jet out to clean in there because they rust in and just can't get them out. Carbies for them are not too expensive. Check for spark. If you have any starter fluid give it a squirt in the carby and that will give you an indication if it is going to run. If you have a socket set and a drill you can try and drill start it if you haven't fixed the pull starter
