Suzuki Kim's idle speed is good, but he can't refuel. What's going on here?

If this is normal when the cold car starts, it is good to warm the car. The same is true for hot cars. Check whether the air filter and carburetor are blocked, clean the carburetor, check whether the mixing ratio of the carburetor is correct, whether the vacuum film of the throttle valve is damaged, whether the oil level of the carburetor is too low or there is something wrong with the oil needle, improper use of the air door, poor spark plug or air leakage in the intake pipe.
