What happened when the elderly started vertically with a four-wheel 200 water-cooled fuel scooter?

Throttling carbon deposit. When the four-wheel 200 water-cooled fuel scooter for the elderly starts, especially when the car is cold, the on-off valve is insensitive to rotation due to carbon deposition in the throttle, which affects the inaccurate parameters of the mixture concentration or the sensor can not accurately feed back the servo, resulting in the feeling of automatic start-up, which can be solved by disassembling and cleaning the throttle. Water-cooled radiator has water inlet and water outlet, and there are many channels inside the radiator, which can give full play to the advantages of water cooling and take away more heat.
