Flip the carb and check the position of the tip of the rotor control the quality of the mixture. If the screw screws up the power beyond measure, a tip could break and damage the seat or plug the outlet. Try to unscrew the screw. Tip of screw should be easy to navigate (if, of course, visible). If the screw is broken or it got stuck in the tip of the outlet, replace the carburetor. Check the plane flange steel ruler. Angled flange - the result of pulling nuts or overheating. If the flange is not very curved, it can get used to the glass with a paste for lapping valves. While this may be a long and difficult. Again, the alternative - replacing the carburetor. Curvature of the flange, unfortunately, frequent, leading to air leak and poor performance of the carburetor. Check the valve and the axis of the lack of backlash, wear and jamming. Cup wear soft aluminum wall reactor in which the spin axis. Worn body is rough engine operation, the floating-load, jamming in the throttle and changing the level of CO in the exhaust. If the body is worn out bushing axes can sometimes replace a specialized workshop. Otherwise it is necessary to replace the throttle body (if possible). Education of the ring carbon at the point of contact with the throttle body is rich mixture at idle, throttle sticking and loose its closure. It can also affect the work of the second chamber, double chamber carburettor. Check the carburetor body and choke on the absence of displacement or loss of plugs. Check for cracks or damage recoverable in the case. Small defects can be eliminated by using the "cold welding". Check the integrity of the springs for damage and deterioration of control rod attachment. Replace damaged components. Check for wear and scuffing axis control mechanism and damper rods. Wash the carburetor body with a stiff brush and a suitable composition for cleaning the carburetor. Remove the solenoid (or vacuum) valve is idling and wash it with the same composition. Check operation of shut-off needle or plunger, the solenoid valve by attaching to the battery (or using a wire feeding the valve on the car). Attach the valve to the mass and turn the ignition. Repeat several times to check the drawing and pushing the needle stop. Replace the valve if its work is unreliable or cleaning fails. Remove the screws and remove the upper part of the carburetor. If the lid is strong liking, usually fairly light blow with a soft mallet. On most carburetors seal the float chamber is removed with the cap. Check the flatness of the surfaces to connect with a steel ruler. Otherwise, you can verify this by removing the gasket and aligning the docking surface. A slight curvature is compensated by a gasket, but a serious need replacement carburetor. Curvature of the docking surfaces of carbs - common and cause poor engine operation. Check the white sediment in the float chamber. This is caused by a reaction of aluminum alloy for the presence of water. If there are deposits in the float chamber, and probably in the canals of carb a fair amount. Need to seriously think about replacing the carburetor, since washing of channels is very problematic, time-consuming be inadequate result. Remove the top gasket, float, float, and the axis of the needle valve. Anti-vibration ball (if installed) must have the freedom to roam. Tip of the needle should not have the wear and projections. If possible, replace the bronze needle Viton. The float must not have damage and it should not simmer fuel (shake it, or submerge in water and watch for bubbles). Defective float replace. Never attempt to repair the floats by soldering, to increase its weight is unacceptable. Worn float axle replaced. Remove the front fuel filter, clean it with a camera from dirt and sediment. Remove the screw of the mixture and check for damage to its tip. Typically, the accelerator pump sprayer body pressed into the carburetor. Carefully remove it and shake it. The absence of noise produced by a ball valve, said on his hang. Weber carbs on the early performance of the valve of the accelerator pump. Remove the valve from the housing and remove the spray from the valve. Shake the valve - hovering ball will not make noise. Check sealing pellets. If the shot is sitting loose, or lost, the valve job, at best, will get worse. Ball intake port in most carburetors Weber installed in the channel and sealed. Gently shake the carburetor body - the lack of noise the ball says it sticking. The only way out - replaced the carburetor. Check for wear of the cam roller and the accelerator pump. Disconnect the lid otuskoritelnogo pump, pump processing, mineral processing valves, starting aperture diaphragm and other devices, if installed. Diaphragm must not be stretched, torn or damaged. If the diaphragm is rubbed, it looks intact, but the fuel passes through the pores of the material and enriches the mixture when it is not required. Remove the idle jet, main jet and emulsion tube. Emulsion tube is usually performed in conjunction with the air orifice and screwed into the emulsion well. In some cases, the device nonseparable. Jets need not be oval, scored pronosheny and varnish deposits. Make sure to clean the channel of the float chamber in the emulsion well. Check the calibration of the nozzles with the specifications. Under the previous repair specialists 'high' class could set up other jets. If set enrichment valve, ball valve in his bronze should lock outlet. Ponazhimayte it clockwise with a screwdriver - it must be able to move. A defective valve replace. In some carburetors Processing bronze valve body castings soldered at the carburetor and remove it is not possible. Defective valve requires replacement carburetor. Remove the screws and remove the throttle body with the main building (if they are separable in principle). When worn throttle axes can replace them with their housing. In Weber carburetors and if you want to remove the primary and secondary diffuser from the housing. The company produces Weber for this special puller. Check at least their tight fit in the housing. If they are taken proslablena, the defect is removed by rolling. Remove the telescopic pull starter (if available). The mechanism must operate without jamming, wear should not be. If you pull clogged, it can be washed in a solvent, the lack of a positive result requires replacement of traction.
