To set the carburetor before competent to check the ignition angle. Engine performance and economy are directly dependent on the installation of ignition. Unable to professionally repair a carburetor, not paying attention to the ignition system. To measure the POPs have to use strobe and data on different motors taken from the professional guides that are sold everywhere. When the distributor vacuum regulator mounted ignition, then you need to know exactly under what conditions the regulator enters the vacuum. In total there are two main options: vacuum enters the regulator only after slight pressure on the gas pedal. The vacuum is constantly supplied to the regulator at routine motor. In the late 80s and early 90s on foreign cars, complex design of the vacuum connections to the mechanical ignition control. The meaning of these complications consisted in changing the power vacuum acting on the regulator, depending on engine temperature. In addition to the set of tubes, in these constructions used different thermoswitches and actuators, valve delays and collectors of condensate. But even the most complex wiring diagram applies to the first or second choices. In the end, the designers abandoned the ignition systems unreliable mechanical control and now in modern cars operate unregulated electronic components, automatically controlling ignition. All this is said to be clear - the most complicated system of vacuum connection can be simplified if you know the conditions under which the regulator should do a vacuum. Serviceability of the vacuum regulator to check the ignition distributor tube, one end of which is put on the regulator. When running at idle speed the engine to create a vacuum in the tube. Engine speed should increase to 100-200 r / min. This means the serviceability of the vacuum regulator. Before adjusting POPs need to make sure that the vacuum to the regulator comes just as it should. If you skip this step, the alignment of the plug can be wrong. This mistake is often repeated staff car service. To adjust the ignition with the strobe on the engine installation, there are a label or a graduated scale. Search these labels need to crank pulleys in front of the engine or in a window on the flywheel. These places on the engine are often covered with a thick layer of mud or rust. Therefore, before measuring all should be well cleaned, and touch up marks. Adjustment should be made to warm the engine running at idle. By turning a small corner of distributor, combine the necessary tags for blinking strobe light. A list of recommended plug for some cars manufactured in CIS countries: All the classic "Lada" and "Field" - 5-10 degrees before TDC (top dead center). VAZ-2108 and all carburetor modification - 10-12 degrees before TDC. "Muscovites" - 10-20 degrees before TDC. "Gazelle", "Volga" - 5-15 degrees before TDC. "Tavria" - 5-10 degrees before TDC. In all the above vehicles on tramblere vacuum appears when you press the gas pedal. These production plants are different from these values. But practice shows that these angles are optimal timing for capacity and efficiency of motors. After the adjustments required to test short trip driving of a car. Detonation "knock your fingers" is allowed only during heavy acceleration, and time can not last more than a quarter second. With smooth acceleration knocking should not be. Riding with long intervals of detonation knock can lead to serious breakdowns of the cylinder-piston group. After a quality repair the carburetor, while the control visits may knock detonation, even if the timing is fine. In this case, do not rush to install a later ignition. A large number of soot that had accumulated in the cylinders during operation of the vehicle with a faulty carburetor, can cause detonation knocking. To burn off carbon deposits from the cylinder enough for 10-20 minutes journey from a working control system, power supply and plugs. Establish a later ignition should only be when the trip did not remove the control detonation. The various factors affecting the appearance of detonation or gain include low-octane gasoline, early ignition timing, a great engine temperature, throttle position (degree of filling of the cylinder) and a large amount of soot in the combustion chamber. When the humidity of the air entering the engine, detonation is weakening. This is because the moisture in the air significantly reduces the thermal regime of the engine. A list of recommended plug for some cars: Audi: Audi - release of the first half of the 80s, carburetor Pirburg 1B - 10 degrees. Vacuum - after pressing the gas. Audi with the carburetor or Kayhin Pirburg 2e2 - 16-22 degrees. Vacuum - permanent. Audi's carburetor Ekotronik 2EE - 16-22 degrees. Vacuum - permanent. Volkswagen: Jetta, Golf, Passat with the carburetor Pirburg 2e2 - 16 - 22 degrees. Vacuum - permanent. Jetta, Golf, Polo with the carburetor Pirburg 2EZ - 20-25 degrees. Vacuum - permanent. FORD: Serra Weber carburetor with ISC - 6-10 degrees. Vacuum - permanent. Connected to the computer. Serra, Transit from a carburetor Motorkraft - 8-10 degrees. Vacuum - after pressing the gas. OPEL: Cadet with kabyuratorom Pirburg 1B - 10 - 12 degrees. Vacuum - permanent. Connected to the sensor load. Ascona with carburetor Varadzhet - 10 - 12 degrees. Vacuum - after pressing the gas. Record with the carburetor Varadzhet - 10 - 12 degrees. Vacuum - after pressing the gas. Omega with the carburetor Pirburg 2EZ - the ignition is not adjustable. Vacuum - permanent. Connected to the power plug. Warburg with the carburetor Pirburg 1B - 18-24 degrees. Vacuum - permanent. SKODA with carburetor Pirburg 2EZ - 2-10 degrees. Vacuum after pressing on the gas.
