What's the matter that Feizhi 250 motorcycle can't refuel until it reaches 70 yards?

There are many reasons why you can't afford to refuel, usually related to the carburetor. However, if this happens only when it's cold, it's normal if it doesn't burn enough and you can't afford to add oil when it's cold. It's normal after it's hot. When the cold car starts, pull the air door and warm it up for a while before you go. If the hot car can't add the accelerator, check and clean the air filter and carburetor respectively, and check whether the spark plug is normal, whether the valve clearance is too small, whether the intake pipe leaks, whether the gasoline is deteriorated, and whether the exhaust pipe is blocked. Check whether the carburetor is blocked, the mixing ratio is improper, the valve clearance is too small, and the spark plug and gasoline are defective. If this happens only at the beginning of the cold car, it is normal and there is no need to repair it. Just pull the damper or preheat it a little. If the hot car is like this, you can check it according to the above.
