Carburetors "Ozone"

Carburetors "Ozone" are distinguished from other models of carburetors incredibly simple and reliable construction. Developed in the late 70s, the carburetor, even at the beginning of the XXI century is set on cars "Lada" virtually no change in the structure. In addition to the Soviet "classics" of this device is well suited to a large number of petrol cars of foreign production with an engine capacity of up to two liters. It is believed that the carburetor "Ozone" can be installed in cars only with a longitudinal engine layout. But I happen to repair some of the foreign cars with transverse engine, which operated for a long time with the carburetor "Ozone" without any complaints about the operation of this carburetor. 1. Screw adjustment of the mixture. 2. Adjustment screw quality of the mixture. 3. Adjusting screw set the initial throttle position of the first chamber. Position the throttle first and second chambers in a free state should be completely closed. But the edge of the throttle should not be jammed at the time of their discovery. The adjusting screw is used to eliminate jamming edge flaps, but flaps state should be as closed. Adjusting the system idle should be done only when the correct position throttle. Adjusting the initial position of dampers is best done at the bottom of the carb disconnected. 4. The tube is connected to the vacuum regulator ignition. In addition to its primary function, this handset can be used to check the throttle position of the first chamber. With a little throttle in the tube begins to emerge dilution (assuming that the tube is not clogged sludge). Before adjusting the idle speed to ensure no dilution in the tube. 5. The fuel nozzle system idling. Index - 50. This nozzle is installed in a simple holder, which can be made in large or small version, and also occurs in the solenoid valve. During repair the carburetor to check the status of planting a conical nest, which nestles jet idling. To do this, unscrew the nozzle and using good lighting, carefully inspect the mounting slot in the middle of the carburetor, which should be right round. If you notice a violation form or scoured channels on the surface of the conical nest, it means that the fuel emulsion or simply put - gasoline enters the system past the idle fuel jet idle. This in turn leads to a significant, uncontrolled pereobogascheniyu working mixture idle. In this case, the only solution is to replace the middle part of the carburetor. Violation of the sealing cone is more common in the carburetor with a solenoid valve idling. 6. The fuel filter at the inlet to the carburetor. 7. Pump the accelerator. Malfunction of the pump is the same for all carbs: clogged nozzle gap diaphragm, the damper stuck or ball valves, pumps lead to failure of power when accelerating. In addition to the car "Lada" can be an accelerator lever grazing for housing the intake manifold. Place of grazing can be cut down with a file. 8. At this point, a metal screw cap is a mixture of quality adjustment in the air. The screw is hidden under a metal cap to restrict access to nesanktsionirovany random curious. Most of the carbs you can return to normal life without resorting to adjustments in the air. But sometimes drill out the plug in order to achieve a normal adjustment in cases where the fuel mixture is either very poor or very rich and spiked control the quality and quantity does not lead to normal results. The screw adjusts the air flow into the system idling. If you lean to fully tighten the screw, and rich - twist off, seeking signs of a poor mix. The rotation of the screw trimming should be done cautiously, in small portions (1 / 8 turn) and after each small rotation is necessary to check the carburetor adjustment screw the quality of the mixture. 9. Under the screw cap is the screw that adjusts the amount of opening of the choke when the elongated handle "leaks." The value of the opening of the choke should be ~ 3-5 mm. 10. Fuel fitting lid is pressed into the body carburetor. During the operation can take place weakening press-fit, fitting can easily pop out while driving and there will be fire. Therefore, for the verification should be easy to knock the hammer on the ends of the tube and hammer it into place. 11. Vacuum opening drive of the second camera. After installing the carburetor, you must manually check the ease of flap opening in the second chamber is fully pressed the gas pedal. Lever valve could contact the housing and the intake manifold it will lead to a significant drop in engine power. 12. Adjusting the gear lever controls the throttle and air dampers. Bending the lever, you can set the necessary value of the throttle valve in a fully extended arm "choke" (1 mm). Adjustment is made to the carburetor removed. 13. Damper lever of the second camera. 14. Adjusting screw set the initial throttle position of the second camera (see number 3). 15. Tube ventilation of crankcase gases to idle. The ventilation system should be clean and easily purged. On the axis of the throttle of the first chamber is a plastic spool ventilation system. 16. Telescopic rod control choke. Tight spring or jam moving parts to this craving leads to a small opening of the damper and the result is pereobogaschenie working fluid at the speed of the engine warms up. 17. Choke lever must be firmly secured to the axle. Loose lever makes it impossible to accurately adjust the value of opening the choke. 18. The bottom flange of the secondary carburetor. In the operation is arching the lower surface of the flange, which can lead to significant air leak at this location. This is disruptive: the stability of the idle speed and the vacuum opening drive of the second camera. To eliminate the bending of a curved surface should be abraded by the grinding stone flange with a wide side surface. Pre-need pliers to remove the body from three brass pipe. Not to bend the pipes, before excavation to be inserted into the drill tubes of appropriate thickness. On the intake manifold under the carburetor is the drain pipe, which is designed to drain the excess fuel. The loss of the tube or the belt will create significant air leak and deteriorate the stability of the idle speed. Adjusting the carburetor without the gas analyzer is under option A (see here - "Adjusting the idle speed").
