1. Prepare the vehicle for operations (see "Preparing a car for maintenance and repair").
2. Remove the air filter housing from the carburetor studs (see "Air filter housing - removal and installation").
3. When the gas pedal is released, the primary chamber throttle valve should completely cover the opening of the mixing chamber. The assistant presses the pedal all the way down, and the valve should open completely (take a vertical position). If necessary, adjust the position of the damper by changing the length of the drive rods.
4. First of all, we measure the distance between the centers of the ends of the transverse tie rod B (see fig. p. 5), which should be 80 mm. If necessary, remove the rod and, having unsecured its tips with an 8 mm key, adjust the rod length. Lock the tips and install the rod in place.
5. Having removed the tip of the longitudinal rod of the drive A from the hinge of the intermediate lever and having loosened the lock nut, we change the length of the rod, achieving a vertical position of the throttle valve.
The original is available on the website (VAZbook)
6. Having set the vertical position of the throttle valve with the gas pedal pressed all the way down, we put the tip on the intermediate lever joint. We lock the rod tip.
