What's the matter with asking riders to step on the brakes and turn off the fire?

Landlord, the car stalled at idle speed: first check whether the throttle should be cleaned, then check whether the idle motor is stuck, and third check the gasoline pump. There are two situations in which the car suddenly shuts down, either the oil is cut off or the fire is cut off. Don't disassemble the gearbox in a hurry, clean the throttle first. Maybe it's too much carbon. Problems with the gearbox can be answered online.
