Hi, I recently got a 50s scooter from a colleague. It was a Benzhou YY50 something (can’t read it properly). The scooter had been unused for him for 2 years in the garage. The ride to my home (about 30km) was no problem. The scooter ran like a 1. But then it started. On the next morning I wanted to go to work early. The scooter needed a few starts until it got started. As soon as I let go of the gas it went out. So I got a 50s scooter. After 100 meters, the scooter slowed down until it stopped and the engine went off. That certainly recured 10 times until it ran. On the way home then the same game. ALso I googled a bit and found out that you should clean the carburetor. So said the carburetor was cleaned. Result: Everything as before, scooter goes out after 100 meters. After a few checks I found out that the E-Chock was attached to it. In Ebay I bought and installed a NEW carburetor incl. Chocke. Result: The scooter starts now mostly immediately at first time. Then it runs stable with a speed of ~150-1800 u/min. But not for long, then it goes out again. If I start it again, I have to hold the gas again so that it doesn’t go out. I can’t change much at the STandgas either, because otherwise it turns too high. If I drive, that’s the same again. e Problem as before: The scooter goes after approx. 100 meters from unf drives properly only when it is “warm”. I don’t know what else it could be. Do you have an idea? Greeting, dsiggi
