Roller went out during the ride and doesn’t start anymore

Hello, I was on a country road earlier, in order not to be sooo a block of cars, I drove for the first time at all with full throttle and all of it. So by that I mean, the throttle flap was completely open. Really what didn’t bring it, I drove 50 according to Tacho, it went uphill. So, suddenly the scooter went out, I guess that anyway, because there was absolutely no gas and the engine brake was stronger than usual, so probably also standing throttle was gone. before I came to stand, I then pressed the electric starter, when I then stood, the scooter ran (again). I drove the remaining 4 kilometers without any problems and without incident home. Arriving at the door, suddenly the scooter began to stutter, well, to stutter. The speed went up and down, completely arbitrary. I also could not give any more gas, he threatened to escalate and it smelled more like gasoline. I then thought that he might have sparks, or he does not ignite, since the ZK so I let the scooter cool down first and then started, it started, but still this funny ignition oscillation. I let him do something, he went out twice, but then he ran again again. I thought that the candle burned out and I could give it normal gas in the stand. When I wanted to take it from the stand then the whole thing started again and it went out. But then invalid. So again helmet compartment, ZK out, was moderately black, so I wanted to take it from the stand, it started again and it went out. another built-in, no success. A 3rd built-in, still no success. Since I was of the opinion that the candle looks “too dry”, I once opened the carburetor, but there was nothing eye-catching in it. The float is in general and both nozzles and nozzle poles are free. Then the ZK held to mass and … no sparks. So everything was assembled again, went to a darker place, result: no spark. My question: Can an ignition coil just die like that? So urpl Or am I to blame for driving full throttle? How can I test whether it’s the ignition coil, the CDI or maybe even the Lima?
