How to adjust the idle speed of motorcycle carburetor

Warm up the car first, then slowly tighten the throttle adjusting screw to make the idle speed rise to 2000-3000 rpm, adjust the stirring screw (generally, turn it for about 2.5 rpm where it is tightened) to make the engine speed reach the highest point, and finally slowly loosen the throttle adjusting screw to make the idle speed drop to about 1000- 1500 rpm.

Note that the carburetor has two adjustment screws, the throttle adjustment screw is visible and the mixed adjustment screw is not visible.

As a precise mechanical device, carburetor uses the kinetic energy of inhaled airflow to atomize gasoline. Its important role in the engine can be called the "heart" of the engine. Its complete device should include starting device, idling device, medium load device, full load device and acceleration device.

The carburetor will automatically match the corresponding concentration and output the corresponding amount of mixed gas according to the requirements of different working conditions of the engine. In order to mix the mixture evenly, the carburetor also has the function of atomizing fuel for the normal operation of the machine.
