In order for the driver of a car with automatic transmission to have such an opportunity, the above-mentioned system has been designed. Its main elements are the gas pedal cable between the gas pedal and the shift lever on the gearbox and the second cable, "carburetor cable", between the box and the throttle lever. During normal driving, the driver, by depressing the gas pedal, opens the carburetor throttle from the closed position to full opening. When you press the gas pedal, you feel resistance. The carburetor throttle is fully open. Pushing harder on the accelerator increases the resistance of the shift lever spring on the gearbox and causes the gear to shift to a lower gear, allowing better use of the engine's power reserve. The result is better dynamics when accelerating.
Cable adjustment - carburetor 2E2
1. Start engine and warm up to operating temperature and normal idle speed. This ensures that the throttle is in the correct position for adjustment.
2. With the gear selection lever in position P, loosen the adjusting nut of the gas pedal cable and disconnect the cable from the gearbox (pic. 6.25).

1 - carburetor; 2 - transition spring; 3 - throttle cable; 4 - gas pedal cable; 5 - gas pedal; 6 - limiter; 7 - spring; 8 - protective tin plate; 9 - switching lever.
3. Remove the air filter assembly.
4. Loosen nut 4 that secures the carburetor cable to the bracket on the carburetor (pic. 3.30).

5. Turn the throttle lever 2 so that the carburetor adjusting bolt does not touch it, then fix it in this position, propping it up with a screwdriver.
6. Remove and disconnect the reduced pressure pipes from the four-output servomotor 17 (pic. 3.21).
7. Connect the reduced pressure pump to the lower connection (A) on the servomotor. Ports B and C must be open (pic. 3.21).
8. Using the pump, create a reduced pressure so that the servo pusher remains in the overload position and there is clearance between the adjusting bolt 3 and the servo pusher 5. Pull the metal protection of the throttle cable from the carburetor to eliminate the gap, and at the same time leave the throttle closed and set the lever in gear, based on the overload limiter. Squeeze the nut 4 of the carburetor cable clamp so that it docks with the bracket and is not tense, then squeeze the safety lock nut 5.
9. Reinstall the gas pedal cable, then ask an assistant to press the gas pedal to the gear selection limiter to a lower one. Turn the accelerator cable adjusting nut until the control lever at the gearbox mates with the gear selection limiter to a lower one, then tighten the locknut.
10. To check for correct adjustment, the carburetor servomotor must be in the overload position, and the control lever at the gearbox must be docked with the overload limiter. Press the accelerator pedal to full throttle (before selecting a gear to a lower), then check whether the carburetor throttle lever rests on the full-open limiter. Inlet spring 2 must not be tensioned (fig 6.25).
11. Then depress the accelerator pedal to the full throttle position, to the downshift position, and then check that the control lever on the gear selection limiter is downshifted and the passage 2 spring is compressed by 8 mm.
12. Install the air filter.
