Connection of four oil pipes of pedal Suzuki ue

Talking about the function of the pipe on carburetor. It needs an oil inlet pipe and the oil level is controlled by a floating needle valve. Generally, there are few two, except for a multi-cylinder machine that uses multiple needle valves to control oil, but this application is rare. The second is the negative pressure tube, which is the power of the diaphragm pump. On the vacuum carburetor, the main body will be there, and other carburetors will draw negative pressure into the air pipe. There is no such nozzle on the carburetor.

The third is the atmospheric balance hole of the carburetor, which is above the carburetor oil pool, which means that the carburetor oil pool will not become a closed space and needs to be ventilated to the atmosphere. The carburetor can exhaust gas when it is intake, and can intake gas when the carburetor oil level drops, so as to ensure the internal air pressure.

The fourth is the oil drain pipe. Some people call it waste oil pipe, but its real purpose is "excessive overflow and diversion", that is, when the carburetor oil level is out of control, excess oil will be discharged, otherwise, it will be difficult to fill the engine cylinder or flow to the engine. Others, some will have some trachea, such as bypassing the enriched airway, such as accelerating pump. Others will have some wires, such as electronic dampers?
