A car engine cannot function without fuel supply, or rather, without a well-prepared fuel-air mixture. For this, a carburetor is used, in which it is created by mixing parts of air and gasoline. Many car enthusiasts with carburetor engines often encounter problems with clogging or damage to this device. Repairing it is not particularly difficult and usually comes down to replacing damaged jets or gaskets.
Necessary
- - screwdriver;
- - pliers;
- - keys 10 and 13 mm
Instructions
Step 1
Remove the carburetor. Its design, developed for cars of the VAZ family, provides the engine with a fuel mixture and makes it possible to replace some parts. In addition, the carburetor can be adjusted without removing it from the vehicle. Remove the carburetor only when replacing it, flushing it, or replacing individual parts. For this, no special tools are needed - open-end wrenches 13 and 10 mm, pliers and a screwdriver.
Step 2
Remove the air cleaner, and then disconnect the starting device drive, to do this, loosen the screw securing the air damper drive cable to the lever, and the screw securing the cable sheath to the bracket. Pull it out with the cable from the holes and set it aside. Disconnect the throttle valve drive by removing the plastic hinge from the ball pin, which is located on the throttle valve drive lever of the 1st carburetor chamber. Remove the fuel line and crankcase ventilation pipe. Disconnect the carburetor from the exhaust manifold flange by unscrewing the four body nuts.
Step 3
Clean the work area from dust and dirt, provide good lighting where you will disassemble the carburetor. Remove the float chamber cover. It is attached to the body with 5 screws. Disconnect the telescopic rod and the choke lever; for this, first slightly lift the rod up and out of the groove. Pay attention to the gasket while doing this. After removing the housing cover, access to the air and fuel jets, as well as the float chamber for cleaning, purging and replacing them.
Step 4
Replace the fuel jet, needle valve, float, gasket on the removed cover. From the bottom to the carburetor body through a prefabricated heat-insulating gasket, the throttle body is attached with two screws. When disassembling the carburetor, be careful: the heat-resistant gasket, which is 3 mm thick, is sealed on both sides with thin cardboard gaskets. If not handled carefully, they can easily deteriorate.
