Scooter does not switch to stand gas anymore

Hey people have a China scooter, because the scooter at the traffic light when I gave no gas often went out I wanted to adjust my stand gas, that I did then, I have to say it didn’t do much when I turned on the screw. But the scooter at least did not go out while trying so I read it like that. When I wanted to get out of the house this morning the scooter didn’t want to start no matter what I tried (stand gas was changed when the scooter was warm) al I then turned on the screw no matter how always the same. I wanted to turn on the scooter with the kickstarter but did not go and if very briefly the same with the e starter. This morning I saw that the e Chock cold startes is on the carburettor, but he did not have a cable looked like it is off. On the picture you can see that the yellow green cable is there I think it is from the e hack. Do you think it is because before he went also always before I changed it???? Please help me
