After changing the flywheel throttle, it can't be sprayed out. What happened?

If you change the flywheel throttle, the car won't spray out. The reason is that the flywheel is wrong, and the flywheel has no deflection signal ring. After replacing the flywheel, the car can't stop because the flywheel is wrong, the flywheel has no bent signal ring or the signal ring is in the wrong position. The function of the flywheel includes the following three points: storing energy, stabilizing the rotational speed, ensuring the angular velocity and output torque of the crankshaft to be as uniform as possible, and making it possible for the engine to overcome short-term overload. Driving part: the function is to transfer the rotating force of the engine to the driving wheels through the transmission. Start the engine: the outer edge of the flywheel is equipped with a flywheel gear ring, which meshes with the driving gear of the starter to start the engine.
