Carburetor "Solex" - how is it installed and how is it regulated?

The modern car carburetor is an accurate and complex mechanism that doses the right amount of fuel, mixing it with air and supplying it to the combustion chamber. The construction of the carburetor "Solex" is complicated by the fact that this device consists of many complex functional units and elements that are also intertwined with electronics. This is why many motorists call this mechanism the most capricious of the entire DAAZ family. But is it possible to install and correctly adjust the Solex 21083 carburetor without the help of specialists? It turns out, it is possible.

Mounting the device into the system

Before starting work, you need to take into account that the Solex carburetor is a complicated device, so to install it you will need to buy an additional set of components. Among several methods of installation, motorists note a method without EEPH (an economizer of compulsory idling). As practice shows, installing the device in this way entails an increased consumption of gasoline (by about 6-10 percent). However, by sacrificing fuel, we make the Solex carburetor more reliable. Strangely enough, but the economizer of compulsory idling is a frequent source of breakages in the work of this mechanism. In order not to waste time and nerves on its repair, turn off this device.

To ensure that the electric valve does not block the flow of gasoline into the combustion chamber in the absence of a block, drivers cut off his plastic needle or pull it completely out of the housing. However, experts argue that it will be more humane to connect this device to the electrical system. In this case, the valve completely covers the idling channel with the ignition on.

How to adjust Solex carburetor ?

In general, the adjustment of this element is possible only when referring to professionals, but motorists have found a way to independently adjust the mechanism in garage conditions. Below, we will give you an instruction to improve the dynamics of the car, stabilize fuel consumption and reduce the level of toxicity of exhaust gases.

The first thing we need to do is take out the spring from the vacuum drive of the damper. Then we change the regular diffuser I of the chamber to the one that stands in the second (with the marking 4.5). It is also possible to convert the throttle, changing its drive from vacuum to mechanical. Some experiment with jets to increase dynamics. Just note that this method of debugging is very dangerous for the car, and it is not necessary to do it at all. By increasing the jets, we can lose the entire Solex carburetor, so in order to avoid trouble, follow only the first three ways of adjusting.

If everything is done correctly, an absolutely new, economical car with a lively dynamics and corresponding power can be obtained at the output. All the stages you do with your own hands, without resorting to expensive service centers, which will save your money considerably.
