How is the normal scooter suddenly refueling automatically?

Is your car a new car or a car that has been used for several years? ?

In fact, when encountering these problems, you should not rush to change parts. Sometimes the problem is actually very small, and when you find it, you will feel very funny!

For your question. You have changed the throttle line and carburetor. Then these two parts were ruled out by us! Next, we have to consider the problem of air filtration, although this seems to have no effect. But we will still take the air filter apart and clean it up. Slap it on the ground and blow it if there is a high-pressure air gun!

Then, every time you drive, you have this problem. You tried to slam on the accelerator, but you had to brake. See if the symptoms will go away.
