My motorcycle is Chunfeng 125. How to mix the mixture?

First, lower the oil needle by one grid to see if there is too much carbon deposit. Or whether the spark matching is normal. 5mm, or open the carburetor to raise the oil level 1, but there is a big difference between the two, that is

The front of the adjusting screw of the mixer is conical, which is the same. Screw with a screwdriver, which is looser than other screws. It is used to adjust the throttle opening by screwing in and screwing out the pitch.

Adjust the idle screw first, and then adjust the throttle screw, but the general purpose is to slightly increase the concentration of the mixer on this basis. When the idle speed suddenly becomes high, slowly adjust the mixing screw and remember this position.

If there is no improvement, remove the spark plug.

The adjusting throttle screw is used to adjust the cross-sectional area of the oil passage. Start the motorcycle and adjust the throttle screw so that the engine speed is about 1200- 1500 rpm. From the appearance, the screw of the adjusting screw of the mixer is covered with a spring and a trolley to keep the idle speed at about 2500 rpm, while the front of the adjusting screw of the throttle valve is a plane preheating trolley.

Wait until you can feel the power box heating, no matter what kind of carburetor it is.
