MC13-001 chainsaw carburetor

The complete device of the carburetor should include a starting device, an idling device, a medium load device, a full load device, an acceleration device, etc., to meet the needs of the engine in different working conditions. The air from the outside enters the carburetor after being filtered. The amount is controlled by the change of the choke position. The air rushes through the throat in the carburetor to create suction, sucking the fuel from the float chamber through the nozzle and atomizing it. The atomized fuel and air are mixed and sucked into the cylinder through the intake manifold. The intake of the mixture is controlled by an accelerator pedal, which is controlled by the accelerator located in the carburetor. The amount of oil pumped into the float chamber by the gasoline pump is controlled by the float in the float chamber. The float rises and falls with the amount of oil in the float chamber. When the float chamber is full of gasoline, the float floats up and uses its needle valve to block the oil inlet.
