Carburetors "Solex"

Carburetor "Solex" is one of the most versatile devices that are installed on engines with up to 2 liters. The advantages of these carburetors is simplicity of design, the possibility of its installation on motors with longitudinal and transverse, the cheapness and abundance of spare parts. In recent years often practiced replacement of worn import carburetors new carburetors "Solex". Such a change is made in the case where repair of the old carb is too expensive or not possible at all. The old foreign cars with the new "Solex" get a second life. But "Solex" like any other carburetor has its own "birth defects". 1. Threaded mounting the solenoid valve is sealed with a rubber-load sleeve. Because of the rigidity of the sleeve during tightening the valve is a big load on the threads in the carburetor body. Therefore, frequent failure is the failure threads in the carburetor body, spontaneous untwisting valve or incomplete twisting the valve. Any of these faults leads to a noticeable increase in fuel consumption and a deterioration of driving performance vehicle. To eliminate the stiffness of rubber should be cut a small part of the sleeve to solenoid valve could twist the key without much effort. 2. The most common fault cardinality economizer modes are damaging the rubber diaphragm, clogging the fuel nozzle and vacuum nozzle clogging. Sometimes there is a bending of the outer cover Efficiencies. The cover can easily align the grinding stone. Ball intake valve has a screwdriver slot, but the twist is not recommended - ball valve is pressed into the carburetor body and is removed only to replace it. All faults economizer increase fuel consumption. 3. Accelerator pump fault dips produce power when you press the gas pedal. Clogged fuel injectors and damage to the rubber diaphragm are the most common defects of this mechanism. In addition, attention is directed to a metal button (chempfer) located on the diaphragm. The button should be pressed tightly and do not jam in the down position. If the button is pushed left, the accelerator pump lever to get the slack and start of injection is late by the time the throttle openings. Pump lever should not hang out at any throttle position. Under the injector pump in a vertical channel inlet valve is pressed the accelerator. Clogging of the valve blocks the pump. To get the valve from the vertical channel, you must use a special remover in the form of bottle corkscrew. Instead of a stripper, you can use a long screw-tapping of a good metal. Thin tube injectors are regulated so that a trickle of gasoline did not touch any obstacles. 4. Tube ventilation of crankcase gases to idle. The tube is often clogged with soot. So, before adjusting the carburetor, remove the rubber hose from the tube and check the cleanliness of jet, (the engine is running you can apply a finger to the tube and nozzle when pure, the finger will pull the tube). Adjusting the carburetor clogged tube with ventilation often leads to serious errors and can be considered incorrect. In addition to pure tube to check the purity of the rubber hose that fits over it. During the cleaning of tube fouling can apply a thin steel wire, solvent and compressed air. Cleaned up a drill is prohibited. Drill holes may increase the amount and the result is a strong air intake, which will affect the operation of idling. 5. The tube is connected to the vacuum regulator ignition. This tube can be used to control the throttle position while adjusting the idle speed on a hot engine. The presence of vacuum in the tube indicates that the throttle is opened to a large value. The vacuum in the tube should only appear after pressing the gas pedal. 6. After several years of operation, the deformation of the carburetor mounting flange. This leads to leakage of the intake tract and unstable idle. Align the bottom surface of the flange can be a wide flat file. In addition to the curved surface of the flange on the instability of idling affects curved surface insulating gaskets under the carburetor. 7. Sector manual control device choke requires very careful adjustment. Attention is drawn to the complete opening of the choke. Very tight course sector damper may be due to seizing a rope, a lack of lubrication, heavy spring under the ball detent (8) and a strong spring on the choke lever (9). Riding with concealed air damper increases fuel consumption. 10. Adjusting screw size opening the choke when starting a cold engine. 11. Adjusting screw size throttle when starting a cold engine. Adjusting the carburetor without the gas analyzer is held under option A (see here - "Adjusting the idle speed").
