Carburettor basic setting

Hello dear community, I’m driving a Sym Jungle 50ccm 2t built in 1998. I’m reporting because I have a question about the carburetor basics, i.e. the CO and stand gas screw. First of all: I cleaned the carburetor, because the scooter starts badly and I had the problem that he did not take any gas when starting (to start I had to give full gas). Now I set the stand gas so that it can hold it at all times (I don’t know exactly how far the CO-Schr Aube is outside, but he usually sounds good). But now it is that if I give half-gas already at full speed. Now I wanted to know if that is bad for the scooter now, or if you can drive with the carburettor grounding so, without which you break something. Thank you already in advance! Greetings moritzg928
