Some info please.
Last time it ran?
How long has it sat, unused?
Age of the scooter, miles?
No spark? > 1) Key on brake pulled see a brake light at tail light?
2) Does engine crank over?
3) check spark plug cap for tightness, and the other end of the spark plug wire for the same.
4) try new spark plug?
Report....
