It's probably a fuel problem. Give it a shot of carb cleaner into the carb and see if it fires. If it does you have carburetor problems or fuel delivery to the carb. There is a drain valve on the carb, you can open that and tell if gas is getting into the carb fuel bowl. I've messed with the carbs and wound up finally just buying one and that finally fixed the problem. Also a good battery and small charger are really handy at times like this. There are gobs of youtubes on trouble shooting scooters watch a few and you'll get it running. Come back and tell us what you found and how you fixed it.
Here ya go pick one, youtube....
