The VAZ-2103 cars manufactured in 1972-74 were equipped with 2103-1107010 carburetors. From 1974 to 1976, the VAZ-2103 VAZ-2106 cars were equipped with 2103-1107010-01 carburetors, and from 1976 to 1980, the VAZ-2106-1107010 carburetors. Since 1980, the Ozone 2107-1107010-20 carburetor has been installed with ignition distributors that have a vacuum ignition timing regulator. With old ignition distributors (without vacuum regulator) the 2107-1 ID-7010-10 carburetor was installed, which comes in as spare parts and differs from the 2107-1107010-20 only by the absence of a vacuum take-off pipe for the vacuum regulator. The carburetors with the corresponding ignition distributors are interchangeable with each other.
The main data of the carburetors are given in the table.
The VAZ-21063 vehicles are equipped with the 2105-1107010-20 carburetor, which differs from the 2107-1107010-20 carburetor only in the following calibration data: the diameters of the main fuel jets are 1.07 and 1.62 mm; diameters of main air jets - 1.70 mm; diameters of the pneumatic drive jets of the second chamber throttle valve - 1.2 and 1.0 mm; starting clearances of the air damper - 5+0,5 mm, throttle valve - 0.7-0.8 mm.

The VAZ-21065 car is equipped with a Solex type carburetor 21053-1107010, shown in pictures 10-11 of the album. This picture of the album shows the carburetor 2107-1107010-20.
Carburetor 2107-1107010-20 emulsion type, two-chamber, with a falling flow. The throttle valve of the first chamber is opened from the pedal in the cabin. The carburetor has a balanced float chamber, two main metering systems, a diaphragm starting device, an economizer (econostat) with a pneumatic drive, a diaphragm accelerator pump with a mechanical drive, an autonomous idle system and a transition system of the second mixing chamber, as well as a slide valve device for ventilation of the engine crankcase.
Carburetor 2107-1107010-20 consists of three body parts: carburetor body 13, cover 17 and throttle body 54.
Cover 17 has inlet necks of mixing chambers. Air damper 32, needle valve 26, float 25, fuel filter 27 are installed in the cover.
The starting device is attached to the cover. The air damper lever 33 is connected by a rod to the rack 35, and by a telescopic rod 34 to the three-arm lever 38. Economizer channels are made in the cover (econostat).
In the housing 13, easily removable small diffusers 30 are installed in large diffusers, manufactured together with the sprayers 31 of the main metering systems and the economizer sprayer. The housing contains the channels of the main metering systems, the autonomous idle system, the transition system, the accelerator pump, the communication channel of the starting device with the space behind the throttle. The sprayer 19 of the accelerator pump is installed in the housing; fuel, air and emulsion jets of the above systems.
In the housing 54, the flaps of the first and second chambers are installed. On the axis of the flap of the first chamber, the following are installed: the lever 42 of the throttle valve drive from the pedal, the lever 45, which limits the opening of the flap of the second chamber, the lever 46 of the connection with the air flap, the cam 4 of the accelerator pump drive. On the axis of the flap of the first chamber, there is a valve of the engine crankcase ventilation. On the axis of the flap 51, the lever 49, rigidly fixed, and the lever 48 of the flap drive, connected through a spring to the lever 49 and to the rod 47 of the diaphragm of the pneumatic drive are installed. In the housing, the channels of the transition system and the autonomous idle system are made, the adjusting screws 11 and 9 of the mixture quantity and the quality (composition) of the idle mixture are installed.
