How to clean and maintain the throttle?

Hello, there are two ways to clean the throttle. 1. Take out and clean; 2. Wipe it clean in the car. Usually the first one is cleaner. First, the throttle valve is located in the middle of the intake pipe. After finding it, unplug the plug, then unplug the water pipe, finally unplug the plastic pipe, remove the screw, and then spray carburetor cleaner and clean rag on the rag for cleaning. After cleaning, install it in the original position.
