Who knows what spark's screwdriver is like to remove the throttle? Can you clean yourself?

Yes, it's just a universal screwdriver. You can clean the carburetor by buying a bottle of cleaning agent yourself, but you have never had cleaning experience. It is better to watch others clean it once and then clean it yourself.

The specific method is to disassemble the throttle and spray it directly with carburetor cleaner, which is very convenient. You can also clean the idling motor by the way.
