Piaggio TPH 50 XR no longer starts

Hello Motor-Talk, I’m back again. This morning, when I wanted to go to the vocational school, the scooter came immediately the first time. He ran up next (e-choke), after a few minutes he came down again. I sat down on the scooter and wanted to go to the school, which was unfortunately not like that. The scooter took extremely bad gas or actually did not accelerate at all, nothing. Then he went out already, then I got him once again with the e-starter anbek ommen, but then he went out again. Since then he doesn’t jump any more. Just grade, I got on the scooter –> spark plug was wet (changed recently); petrol tap checked–> tube to the carburettor. if I touch the petrol tap now with the finger, something comes out there, if not touch the gasoline don’t touch, comes also nothing. right so? What can I do? Please help me. Can’t be, that if I didn’t ride a roller for a week, that d he carburettor is so added ?! (carburettor was recently cleaned by a workshop) I am grateful for every advice, I think it’s time to step down the scooter again.
