1 10 motorcycle carburetor cleaning method

Cleaning and Adjustment of Motorcycle Carburetor Cleaning and Adjustment of Carburetor is something that all people who play with cars will often encounter. Remove the carburetor from the motorcycle, first clean the outside of the carburetor, and then disassemble the main components for cleaning (you can use a special cleaning agent for the carburetor). The main cleaning parts are: main oil metering hole, oil level chamber, oil level control needle valve and so on. Thoroughly remove impurities deposited and accumulated in carburetor, such as rust, dirt, colloidal particles, etc. After cleaning, reassemble and start trial operation to observe and adjust the technical performance of carburetor under various working conditions. In addition, after using two cases of ethanol gasoline for vehicles, the carburetor should be checked and cleaned again. At the initial stage of use, there will be a cleaning cycle in the process of transportation, storage and turnover of ethanol gasoline for vehicles, so it is inevitable that some cleaned trace impurities will enter the carburetor through the oil circuit. Impurity accumulation will affect the normal operation of carburetor, so it is necessary to check and clean the carburetor after a period of use. Note: in use, if it is found that the idling speed is unstable or there is self-flameout, it is generally only necessary to check and clean the carburetor; If you feel poor power during use, you only need to adjust the mixture (concentration) of carburetor. Generally, the car is not easy to drive, the parking is not strong and the speed is not good. Everyone will first think whether the carburetor is dirty, so they start cleaning the carburetor. In fact, the most important thing of carburetor is not cleaning, but making necessary adjustments on a clear basis. Such as the mixing ratio. As a car player, not everyone can repair cars. So if there is something wrong with the car, you must call the mechanic. But not all repairmen really know how to repair, especially imported large-displacement multi-cylinder motorcycles. Most of today's mechanics include those who only repair domestic cars. From the maintenance of the carburetor, it is only limited to "cleaning". Actually, some cars don't need cleaning. It's just a few screwdrivers. Just adjust it. However, if you put it in the hands of some repairmen, you will take it apart and look very dedicated and careful. There's no need to waste time. You know, we usually ride a bike, and if we ride it frequently, the gasoline in the carburetor will be changed frequently with the use. As long as the car is on fire, gasoline will flow in various pipes of carburetor like human blood. At the same time, it also plays the role of cleaning at any time. Of course, there are impurities in gasoline. However, just cleaning is actually very simple, as long as you clean all the existing channels of the carburetor. The key is that many friends have cleaned the carburetor several times, and the effect is still not good. This is actually not easy to adjust. Whether the carburetor works well depends mainly on whether it accurately mixes gasoline and air in an appropriate proportion. Spray it into the cylinder in the best atomization state. This series of actions belongs to mechanical action or physical action. So it has nothing to do with cleaning (of course, cleaning is the premise, and the passage is blocked). At present, there are several parts in the carburetor that can be adjusted mechanically and physically: 1. Wind screw: Different models have different positions. The main function is to adjust the air flow to adapt to the correct mixing ratio. Multi-cylinder cars need synchronous adjustment. 6. Synchronous adjustment of carburetor throttle of multi-cylinder vehicle. By adjusting the throttle position of each cylinder, the car can run at the same speed of each cylinder. 3. Adjustment of main measuring hole. Change the oil output by adjusting the size of the main metering hole (basically need to replace parts). 4. Adjustment of main oil needle. The oil output can be controlled by adjusting the up and down position of the oil needle. 5. Adjust the float in the float chamber. The oil level can be controlled by adjusting the up and down position of the float. The floats of some cars are not adjustable and can only be replaced. 6. Adjustment of idle screw. 7. Individual models need to adjust the position of electronic sensors. The above is only the basic adjustment part of most models. You can make corresponding adjustments according to your car to meet the needs of the actual situation. These adjustments are not needed every time the carburetor is cleaned. Again: the most important thing is not cleanliness, but adjustment!
