How to adjust the idle speed of carburetor in Pu Sang?

Start the engine, warm it up for a period of time to make the temperature normal, and properly tighten the idle screw to make the engine idle smoothly.

Turn the mixture screw until it is the tightest, and then screw it out properly. When the engine idle speed is the highest, turn it twice.

Turn the idle screw to keep the engine idle at about 900 rpm, or reduce the speed appropriately.

If you haven't cleaned for a long time, you'd better clean the carburetor.

There are two small screws on the carburetor of the engine, one is to adjust the mixture and the other is to adjust the idle speed. (Idling screws usually have springs)

If the idle speed of the car is high when it is cold, it is normal to drop down when the water temperature of the car is normal; If the engine keeps a high idle speed (the idle speed of ordinary cars is generally between 700 and 900), it may be caused by the stuck throttle. Whether it is a mechanical throttle or an electronic throttle, the opening may be inaccurate due to carbon deposition, and sensors related to engine conditions may send out wrong signals, which will make ECU increase the speed. You'd better go to the repair shop to have a check.

Idle state refers to the working state when the engine is idling. When the engine is running, if the accelerator pedal is completely released, the engine will be at idle speed. When adjusting the idle speed, the speed should not be high and low, otherwise it will cause early wear and tear to the engine, so it is best to adjust it in the automobile maintenance department.
