1 10cc motorcycle carburetor adjustment

If the front end of the throttle doesn't respond, it should be that the throttle line is too long. If the front end of the throttle is a feeling of not refueling, it may be that the mixture in the carburetor is too thin or the position of the oil needle is low. The mixture screw of this carburetor (the one at the bottom left in the figure) is usually screwed to the end, and then pulled out for one and a half turns, but it can be fine-tuned according to the actual situation, and it is advisable to have no more than half a turn left and right. The oil needle of the throttle valve is generally set in the middle grid (usually five grids) when it leaves the factory. During adjustment, the card can be moved down one grid, that is, the position of the oil needle can be raised one grid. The damper is normal when the cold car starts, and its function is to add rich mixed gas when the cold car starts, but after the hot car, because of the improvement of atomization conditions, there is no need to pull the wind. Even if the mixture is rich, it can't avoid the cold start, and it will also pay the price of increasing fuel consumption and other adverse reactions. Don't abandon the beginning of pulling the wind. This is a normal phenomenon. Cold car refers to the temperature of the engine, not the hot or cold weather. If you don't need to pull the wind to start, you don't need to design a damper. Moreover, the engine oil deposited at the bottom of the engine can be fully lubricated to all parts of the engine after preheating for a period of time after cold start, which is very important to prolong the life of the engine.
