Default ys 170 - shutting down

Hi everyone,

After few months tat i try to fix the problem nothing changes so here it is :

The YS check valve :F4088 - image below, with the needle jump out and the engine ofcurse shutting down,
i dont know why the needle came out, i try to put it back and its look fine , its a little hard to put it back beacuse the shape of the needle , after that the engine works fine, its really sounds good and have a good power i hope so , 8000 RPM with 18X10 MEIZJLIK carbon prop,
i use with the soft mount of yamada - supermount 2. always the oil damper jump out too....

well im really confused and i dont know what to do, any idea?

Thanks. Taylor
