Default YS 91 FZ engine problem

Hi everyone,
I have YS 91 FZ engine. I can not stop my engine , I put down the throtle back and checked the valve, it seems that completely closed but my engine was still running, then I changed the gasket set and the small o ring on the valve then it makes the same thing.
Does anyone knows what should I check more or do???
