Adjustment of carburetor VAZ 2108 in garage conditions

The carburetor VAZ 2108 is that detail, without which the G-8 simply can not continue its movement. If you do not have it, you will not be able to go or even get at least the minimum speed. Therefore this part always needs regular diagnostics and repair. One of these processes is the adjustment of the carburetor VAZ 2108. On how correctly you adjust this part, will depend on the car's power, fuel consumption and even the level of toxicity of exhaust gases. Therefore, all work should be done very carefully and carefully. And our article will help you in this.

We adjust the carburetor VAZ 2108

Adjustment of this part is not without preparation. And, before proceeding directly to the process, you need to check the serviceability of the motor itself. Using a special compressometer we measure the compression in 4 cylinders. If the obtained data are significantly different from each other, adjustment of the carburetor VAZ (2108-099) will be useless. The source of trouble lies in the engine itself. If the compressometer has brought the same readings from all the cylinders, we turn to adjusting the carburetor. To start, we start the engine and wait until it gets its operating temperature (about 80-90 degrees Celsius). After the engine has warmed up, we take in the hands a special screw and reduce idle turns to a minimum. You need to adjust until the moment when you feel that the engine is about to stall. Now turn off the ignition and screw the bolt amount of the mixture until it stops.

Further adjustment of the carburetor VAZ 2108 is accompanied by a twisting of the fuel supply needle by ½ turn. After this, unscrew it for one full turn. If the frequency of rotation of the crankshaft is reduced, and when the next twist is increased, you know - the engine is getting too poor mixture. When everything happens the other way around, the mixture comes out highly enriched. In this case, rotate the screw amount of the mixture to where the rises. When, after adjustment, the crankshaft began to rotate more rapidly, we change the standard nozzle to the part with smaller holes. If the engine rpm remained unchanged during the rotation of the screw, you do not need to change anything. Repair carburetor VAZ 2108 is also not required.

Now rotate the bolt until there is a maximum of revolutions. When turning it in any direction the crankshaft began to rotate less, the mixture is impoverished. If you want your car to consume less fuel, you can leave these values unchanged. However, remember that at the same time the risk of overheating increases substantially, since the fuel ignites only at high temperatures.

When the revolutions decrease when the screw is loosened, the mixture becomes uniquely saturated. In this case, the engine will not overheat, but fuel consumption will increase significantly. Therefore, it is always worthwhile to select the average values, so that the adjustment of the carburetor VAZ 2108 was successful.

As you can see, you can configure this mechanism yourself.
