Can the throttle center plate rotate 360 degrees?

The middle disc can only rotate 180 degrees.

The throttle valve is located behind the air intake. When you find the engine air filter, you will basically find the throttle. Every car will be in a different position. The throttle of some models will be covered by the engine cover plate, so it will be more intuitive to open the cover plate for inspection. Open the motor cover and you can clearly see the position of the throttle. To remove the throttle valve, you must first remove the hose connecting the air cleaner and the throttle valve. Both ends of the hose are fixed with circular iron hoops, and the iron hoops are fixed with screws. Loosen the screw to pull out the hose.
