Guo Si Qianjiang Happy 100 How can we not idle?

Remove the carburetor and open it for inspection and maintenance.

Adjust the throttle adjusting screw and air adjusting screw. If there is still no idle speed, remove the carburetor and open it. Use a steel wire with a diameter less than 0.4mm to dredge the idle measuring hole and idle airway, and use a pump to blow all the holes clean.

If there is still no idle speed after installation, it means that the oil level in the carburetor float chamber is too low or the reed valve and crankcase are leaking. Start the engine for inspection. If the choke valve is closed and the idle speed becomes better, it means that the oil level in the float chamber is too low, and the angle of the tongue of the float arm should be adjusted to achieve the purpose of raising the oil level. When there is still no idle speed after closing the choke valve, it means there is a leak.
