Carburetor cleaning throttle valve
Remove the float chamber, float, float needle valve, idle metering hole, main metering hole, throttle plunger oil needle of carburetor, and sometimes remove the adjustment screw of mixing ratio. Be careful not to lose some small pieces. If the mixing ratio screw is removed, please remember the original number of revolutions. Clean the dirt in the carburetor with special carburetor cleaner or clean gasoline, and blow all the spray holes and small holes in the carburetor with air pump or pumped compressed gas. If the blockage is serious, fine steel wire can be used to dredge the blocked nozzle hole, but be careful not to blow the nozzle hole too big, otherwise it will affect the accurate fuel supply of carburetor.
After cleaning the carburetor, reinstall the removed parts correctly. If the mixing ratio screw is also removed, screw it back to its original number of revolutions. The adjustment of carburetor is mainly the adjustment of idle speed and mixing ratio. Adjust the idle speed when the car is hot, depending on the state of the car. It is normal that the idle speed is low or unstable when the car is cold, and it can only be determined after the car is hot. Due to the different brands and models of specific carburetors, the adjustment direction and rotation speed of the mixing ratio screw will be different, but even for carburetors of the same brand and model, the rotation speed of each carburettor is not necessarily the same. The mixing ratio screw has been basically adjusted before leaving the factory, and it generally does not need to be adjusted without special circumstances. If adjustment is really necessary, it should be carried out by maintenance personnel with professional maintenance experience in combination with the actual situation.
