Tip, dont have the throttle open when you kick it as it will kick back real hard.

Learn kick technique, before it hurts you or the engine.
I'll add that if it has the YX150, it probably has the small outer rotor flywheel and too much advance. Remove area I shaded, 4-5mm, flush with shell. And/or you can slot the pickup and move it up/CCW.
