16 How many screws are there on the accelerator of the hacker?

The throttle is fixed with four screws. First, remove 2 screws from the bottom until 4 screws are removed. After removing the screws, the throttle can be removed.

Throttle is a controllable valve used to control air to enter the engine, which is equivalent to the throat and is the gateway to breathe air. The depth of stepping on the accelerator controls the opening of the accelerator, and then controls the air intake. Only in the previous carburetor era, the throttle was controlled by pulling the cable. Nowadays, in the electronic age, the depth of the throttle is judged by sensors, and then the throttle is driven by a motor to change the opening.
