Le Cheng, is the throttle electronic?

Avio throttle valves are all electronic, and there is no idle solenoid valve. Often the throttle does not run at high speed, the throttle opening is small, and there will be carbon deposit on the edge of the valve plate, which shows that the throttle opening controlled by the engine computer does not match the intake air.

Avio's electronic throttle has only a little opening at full throttle.
