Take a taxi, don't refuel, put out the fire. Why?

Can hit, indicating that the car is not a big problem. There are several possibilities for refueling and flameout.

First, the carburetor idle speed adjustment is not good, and there is a transition from idle speed to normal acceleration. If this transition is not properly adjusted, it will refuel and stall. But if your car is always normal, you shouldn't suddenly appear.

Second, the main oil needle falls off, because the idle oil hole is used for idling, so the car can be started, but a large flow of air is introduced when the valve is refueled, but the main oil hole can't inject oil, so it is turned off. This kind of situation is quite a lot.

Third, the choke valve is lowered, that is, the choke valve is in the activated state, at this time, the main air passage is blocked by the valve, and the throttle valve is opened when refueling, but the main air passage is blocked. The specific phenomenon is that the fuel filler door can be added a little, and if the motorcycle engine is added more, it will snore or stall.

Fourth, the air inlet of the air filter is blocked, which is a bit like a choke falling.
