I've had a 126 Vespa for a few years, it hasn't been driven for 7 years.
I changed the battery and half of the gasoline, and on switching on all the lights come on (fare, gas light, oil, horns work etc ...), I turn the key to start and there He does not make a humming noise it lasts a few seconds and nothing at startup, no matter pressing nothing happens.

Do you have any idea of ​​the failure?

Thank you for your help.
