What should I do to clean the throttle in Pu Sang?

When cleaning the throttle valve, first remove the intake throat to expose the throttle valve, remove the negative electrode of the battery, turn off the ignition switch, straighten the throttle plate, spray a small amount of "carburetor cleaner" into the throttle valve, and then carefully scrub it with a polyester rag or a high-spin "non-woven fabric". Deep in the throttle, you can hold a rag and scrub it carefully where your hands can't reach it.
