125 how to adjust the carburetor of motorcycle plunger throttle? If you know, please tell me. Thank you.

1. If you want to adjust the idle speed, look near the throttle line. Generally, the carburetor idle speed adjusting screw is under the accelerator cable. 2. Under normal circumstances, it is not necessary to adjust the oil needle; It is troublesome to adjust the oil needle, so it is necessary to remove the whole carburetor (pay attention to the cleanliness of the carburetor); Unscrew the end cover connected with the throttle cable, remove the spring and pull out the throttle plunger; There is a V-shaped clamping spring at the upper end of the plunger. Remove the V-clamp spring to adjust the height of the oil needle (through the ring groove at the end of the oil needle).
