Carburetor maintenance

The maintenance of carburetor is actually to keep the carburetor factory cleanliness, which is a carburetor quality evaluation of a key index to control, using a variety of advanced equipment and technology in the production of each link for strict control. In order to ensure the normal use of the carburetor, it is necessary to pay attention to the normal maintenance of the carburetor: regularly clean the carburetor, keep the carburetor oil channel, airway clean, small aperture unobstructed. It is also very important to extend the service life of carburetor. Many performance problems can be solved by cleaning the carburetor regularly.

1. Carburetor is a key part of the engine. Minor changes may affect the performance of the vehicle. Therefore in the carburetor disassembly process, to use appropriate tools, and the strength is moderate, to prevent parts deformation. The disassembled parts should be arranged in order to avoid missing or misassembling in assembly.

2, carburetor cleaning should be carried out in a clean site. First, clean the carburetor surface, internal parts cleaning can use carburetor special cleaning agent or industrial gasoline. In addition to impurities, pay attention to cleaning the surface of the parts of the gasoline gum. Clean the parts with compressed air blowing, can not be used to produce a burr cloth or paper wipe, to prevent re-pollution. Block the hole is forbidden to Pierce steel wire and other hard objects, to prevent changing the aperture of the carburetor performance change, should use gasoline or compressed air cleaning out.

3. In the carburetor assembly process, tighten the float chamber connection screw, carburetor and engine connection screw in one step, but must be tightened several times. Generally, the tightening torque is between 12n. m and 15n. m. Otherwise, the joint surface deformation, leakage or leakage phenomenon. Tightening torque of orifice measuring parts is generally between 1.5n.m and 3.0n.m. Excessive tightening torque will damage the thread, leading to deformation of parts and even metal chips, causing secondary pollution and affecting the performance of carburetor.

4. In the process of cleaning the carburetor, if there are more sediments in the carburetor float room, it is often caused by the failure of the gasoline filter. At this point to check the gasoline filter, if confirmed its failure to clean or replace a new gasoline filter.

5. If you do not use the motorcycle for a long time, please exhaust the fuel in the float room of the carburetor to prevent the condensation of gasoline colloid deposit and cause the carburetor failure. It is especially emphasized that: because the position of the idle speed adjustment screw on motorcycle emissions, idle speed, transition, fuel consumption and other performance have an important impact, carburetor cleaning generally prohibit the rotation of idle speed air adjustment screw. If it is really necessary to remove the idle speed air adjusting screw, the adjusting screw should be screwed to the bottom first, remember to screw in the number of turns (accurate to 1/8), the assembly as the original number of turns back.
