It is normal for scooters to have this situation, but if it is not a scooter, there may be something wrong with the carburetor. Check whether the throttle and oil needle are stuck, whether the throttle pipe and throttle handle are too tight to go back, whether the valve clearance is too small or there is slight air leakage in the intake pipe, and whether the carburetor mixing ratio is wrong, which may also lead to the slow decline of idle speed.
