Sorry, I know there are already some of these threads and I tried them all and everything…so I hope that I can make a difference with a proper thread …. I bought a Piaggio Zip 50 2 clock from classified ads. The scooter was handed over to me in the middle of a city so I did not take a test drive. I got it with a gentle kick and it sounded normal, so I loaded it into the car and pulled my way mighty big mistake he. It turns out that you can kick on the scooter in the cold state, but he runs out after a short time. Then he doesn’t go to no matter how to org and kick. If you wait a day he starts again, but again only for a minute. In one minute the scooter has power and everything, you can turn it up etc., so he doesn’t drain when you give gas, he drinks off when he gets warm I think, or after some time… Everything you can do as a layman I already tried. Ignition spark is there, jets are clean, fuel runs into the carburetor…the carburetor looks like new…what could not be right?
