One of the main devices that ensures stable operation of a carburetor engine in all modes is the carburetor. Not so long ago, domestically produced cars were equipped with a fuel supply system using this device. Therefore, almost every owner of a “classic” has to deal with carburetor repair and adjustment, and for this it is not necessary to contact a service center, since the necessary procedures are easy to do with your own hands.

Introduction
Owners of domestic vehicles, such as, for example, the VAZ-2103, quite often try to fix the car with their own hands. Despite the fact that modern service stations are located on almost every corner and by turning to qualified specialists one could avoid wasting one’s own time, many are in no hurry to solve their problems in this way. Some self-taught craftsmen independently carry out such complex operations, which include adjusting the VAZ-2103 carburetor. Of course, in order to do something like this with your own hands, you need not only free time and patience, but also important and useful knowledge regarding the design features of the device in question.
To adjust the VAZ-2103 carburetor, free time, patience and knowledge are required
In the material below, we will consider the principle of the design of the carburetor of the domestic VAZ-2103, its configuration and adjustment.
What problems in the operation of the VAZ-2105 may indicate the need to adjust its carburetor
The design solution of the carburetor on the VAZ-2105 is aimed at ensuring continuous operation of its engine. However, some circumstances can cause the device to malfunction:
- poor quality fuel;
- incorrect operation of the components of the mechanism;
- natural aging of parts, components and materials from which they are made.
The following malfunctions, which many VAZ-2105 owners may encounter, clearly signal that something is wrong with the carburetor. And it needs adjustment or even repair.
- The car, idling, suddenly stalls.
- The next time you press the gas pedal, acceleration does not occur immediately, but with a delay. Over time, isolated situations “enter” the system with a gradual increase in the interval between applying the gas and increasing the speed of the car.
- Intermittent engine operation, which becomes more noticeable in high gears.
- Increased consumption.
- It is difficult to start the engine after a long period of parking.
In all situations, experienced mechanics begin by removing the device to flush, clean, and purge jet clearances. Low-quality gasoline and failure of filters often cause clogging of the holes. Through them, the fuel mixture incorrectly enters the system, causing various problems.
The smell of fuel in the cabin or flooding of spark plugs may indicate that the carburetor of your VAZ-2105 is not working correctly and needs not just cleaning and purging, but adjustment. For beginners, it is better to turn to specialists who will competently perform all types of work. Experienced car owners do the adjustments themselves.

| Author: Vlad (Tolyatti) Crimea B25 (178.45.168.—) Date: 05-03-12 02:27 A little off topic from boats. The carburetor on my car was completely screwed up. Engine 2101 1200 cm3. It was 2105. DAAZ. I have a 2107-1107010-20 that has never been used, also a DAAZ. There is from 21083, in principle, still alive. Only the landing plane was curved. I spent the whole evening leveling it yesterday, I think it was level. Tell me what is better to put. And what pitfalls might there be (except for connecting gas drives, choke, fuel hoses on 2183) I read all sorts of auto forums. They write who does what. |
| Author: Anatoliipif (2.93.163.—) Date: 05-03-12 02:33 Hello. VAZ 21083 will do. Drive from NIVA. Problems in winter - until it warms up, it won’t run. Good luck. Anatoly. |
| Author: Oleg 1974 (—.broadband.corbina.ru) Date: 05-03-12 03:54 Hello everyone! Better put 2107, believe me, this is the best option. The 21083 carburetor sucks, and for the classics you need to install different jets, redo the rods, etc. And 2107 will fit without problems, just don’t touch anything inside, the jets should remain as they are. I once made a living by repairing carburetors for quite a long time, so trust my experience. |

The difference is in the location of the float chamber. If you put carb 2108 on 2101, then the level in the float chamber will change when driving uphill and downhill.... |
| Author: Bubble with PDA (—.cust.tele2.ru) Date: 05-03-12 04:51 But the nivovods from 21073 don’t know that their level is changing))). And the Solex 21051 was the export five. For the vehicle: put 21083, rods from Niva 21213. Be sure to connect the heating element of the primary chamber to the hose coming from the manifold - without it it’s bad. And don’t listen to anyone - Solex is better than Ozone. |

| Author: Maslov (—.opera-mini.net) Date: 05-03-12 05:36 When I bought a VAZ 2001 11 years ago, I installed contactless ignition and a V8 carburetor at 1100. The positive thing that happened was that it started well in winter and straightaway. After sitting in the garage for a couple of weeks, since I rarely drove for the last three years, I came, pumped up the gas, pressed the gas pedal 15 times and it started. I could start an argument. The carburetor did not fill the spark plugs. Somehow I tried to start the 7 in this way, it wouldn’t start, I had to pull the choke and not accelerate at all. Consumption at first (2 years) was 7.2 liters. The bad news was that the idle jet was constantly clogged. In 9 years I changed three jets. And indeed, during a long descent, when braking at the bottom, it stalled. So I sold it last year. In stores they sell a kit for installing from eight to classic. |

What do 21073 and 21051 have to do with it. These carbs were designed for a longitudinal engine arrangement, unlike the figure-eight carb. Carbs 21073 and 21083 differ, among other things, in the float chamber rotated 90 degrees. |
| Author: s494 (—.broadband.corbina.ru) Date: 03/05/12 05:55 Since 1994, I know that eight-wheel carbs are installed on classics and they drive happily, without being driven by how the float chamber is located. If we assume that the level changes in such a way that it is noticeable for the operation of the engine, then a classic car with its original carb should stall in turns due to overflow or lack of fuel... well, this is so insignificant, because you yourself understand, why argue about it... |
| Author: lednic606 (85.26.164.—) Date: 05-03-12 06:37 Another “note” from experience... Solex is very sensitive to dirt in gasoline, be sure to install 2 fuel filters in a row, “troubles” will disappear. |
