Carburetor 2106-1107010 emulsion type, two-chamber, with a falling stream. It has a balanced float chamber and a crankcase exhaust system for the throttle valve (see fig. 2-81). The idle system is equipped with heating of the throttle zone and an idle jet solenoid valve in the primary chamber (see fig. 2-82). Leverage provides consistent throttle opening and choke has a diaphragm starter for cold starting (pic. 2-83). accelerator pump (pic. 2-84) - diaphragm type, with a mechanical drive, supplies fuel to the primary chamber.

Carburetor 2107-1107010-10 has other calibration data (see table 2-6), enrichment device (econostat), secondary chamber throttle actuator (pic. 2-85) and a modified idle system (pic. 2-86). There is no heated throttle body on these carburetors. Carburetor 2107-1107010-10 is fully interchangeable with carburetor 2106-1107010 and can be installed instead of it on cars manufactured before 1987.

The carburetor 2107-1107010-20 differs from the carburetor 2107-1107010-10 in the changed diameters of some jets and the introduction of a pipe for supplying vacuum to the vacuum regulator of the ignition distributor. This carburetor can be installed instead of carburetor 2106-1107010 on cars manufactured before 1980. But instead of a conventional ignition distributor (without vacuum regulator) it is necessary to install the ignition distributor type 30.3706-02, which has a vacuum regulator.
