Under what circumstances must the carburetor of motorcycle be replaced?

Too much oil, not enough power, the car can't turn to high speed, which shows that the chemical oil-gas atomization is very serious, and the low speed is normal or too high, but the high speed is too thick, so it is difficult to start after dilution, and the high speed is improved, but it is easy to start after concentration adjustment, but the machine can't speed up if it eats too much oil. This chemical oil and gas has been worn for too long, and it is difficult to maintain. It is better to replace it.

If the motorcycle is not used for a long time, it is necessary to empty the fuel in the carburetor float chamber to prevent the gasoline colloid from depositing and condensing, resulting in carburetor failure. In addition, it should be emphasized that the position of the idle air adjusting screw has an important influence on the performance of motorcycle such as emission, idle speed, transition and fuel consumption, so it is generally forbidden to turn the idle air adjusting screw when cleaning the carburetor. If it is really necessary to remove the idle air conditioner screw, first screw the adjusting screw to the end, record the number of turns (accurate to 1/8), and assemble it according to the original number of turns.
