From how well the car runs a carburetor, depends on many things. And it's not just a matter of high-torque engines, or the maximum speed that the iron horse "show" on the road. That is the question of fuel consumption (which is very relevant today). However, like any other high-tech parts of the car, many of the features in the carburetor operates fine, we can say, jewelry items. Therefore, repairs and preventative maintenance of this important body of the vehicle should be carried out very carefully, and it is better to contact the service center. First steps. Check tightness of connections to the details of the carburetor. One reason for the poor quality of the carburetor - it hit the air in "unnecessary" field. Suck the air more often on the docking parts carburetor, the carburetor mounting flange to the outlet pipe and into the ground adjoining the inlet pipe to the throttle body. Often place suction imperceptibly at first sight, therefore, possible problem areas covered soap (if checked in her window is formed at the point of air flow). In addition, the location of leaking at the junction of the inlet to the housing carburetor can be detected by carefully wiping the joint with a clean cloth. If the leak is, it appears on the surface of metal thin film of fuel. At the outlet of a breach of integrity can be seen in the wake of smoke, which remains around the site of decompression. If the point of suction is found, do not rush to dismantle unit. First, try to tighten the nuts or screws (possibly pre-bolts or nuts will slightly drop). Press docked details must be uniformly (criss-cross), otherwise it can skew the fit and thus exacerbate the problem. If such actions do not lead to the elimination of the defect, we will have to change the gasket on the mounting location. Before installing the new seal docked surface should be rinsed thoroughly with gasoline and inspect for damage the surface planes of the connection. If you do not want to bother yourself to the nearest service station zaedte - there is a reasonable cost will change the entire set of pads. Check the strainer. In order to extract the mesh filter, unscrew the cap we will have the fuel filter. It must be rinsed clean gasoline and blow compressed air (you can use a compressor or a conventional pump with special nozzles in the form of a conical tip with a thin diffuser). Conduct examination of the purified filter and pipe supply of fuel. If they are damaged, the details need to be replaced. The float chamber. The next stage - the float chamber. The primary "disease" of the site - contamination of the needle valve cover. In normal operation, the valve moves freely, and the ball in his seat goes without jamming. Contaminated valve is washed and blown with air, too. Next, draw attention to himself float. There should be no liquid in the chamber and it should move freely (without touching the walls). If the float seal is broken, it must be released from the fluid and repair the hole with a strong glue or gasoline substitute. You also need to adjust the alignment of the float (if it is broken). Do it, turning his tongue to the desired position. Orifices and channels. To clean them well with pure gasoline, solvent and compressed air. If you wipe the parts you want to use cloth, use a thick cloth (no lint). Its important to hit the surface hard to see with the naked eye, and the unfortunate consequences may be disruption to the site. If heavily soiled (by jet and channels are often formed plaque-like in consistency resin) used wooden sticks (eg, toothpicks). In no case do not use pins, needles or wires - they are easy to damage the integrity of the surface of parts to be cleaned, and carburetor to work properly will be gone. In contrast to activities such as body repair at an early stage, there is need special care. The accelerator pump. This part is washed in pure gasoline or solvent and blown with compressed air. The next step - to check the free movement of the ball in the slot nozzle. Also check for ease of movement arm and diaphragm carburetor parts (they should move smoothly and without jamming). And the last step at this stage - examination of the sealing surfaces and gasket. Between them should be a snug fit. Parts that have become unusable, replace (not repair, they are subject). Check proper aperture Efficiencies. Another step in the repair or prevention of carbs with economizer power mode - check the diaphragm. She had no visible damage. In addition, you should check the length of the pushrod aperture, and if it is less than the minimum allowed, the device is replaced with a new (complete with a diaphragm plunger). If you decide to seek the services of a beauty salon. Referring to specialists station, remember: regardless of their complexity and orientation of the work (this applies whether the case of repair of fuel system, whether due to body repair, maintenance or running of the car) in the first place is the skill of experts and their relation to that they do. If the work is done "carelessly," for a long time such repairs or preventive maintenance is not enough.
