Does anyone know about Sundiro Holiday scooters?

I have a sundiro holiday and I let someone ride it. They wound up walking it back. There is only 155 miles on it. It won't start now. It has power and gas and oil. It won't start with the electric start or the kickstart. If any has any tips for troubleshooting I would appreciate it.Thanks

check the fuel line to see if gas been shut off.
