Subaru / Robin 20B-62500-08 Engine Float Valve Assembly

The Subaru / Robin 20B-62500-08 Engine Float Valve Assembly operates within certain models of engines. Inside the carburetor the float valve assembly works as an essential element that controls the amount of fuel entering the fuel bowl. The float which is buoyant material moves with the fuel level changes. When the fuel drops the float sinks to allow the needle valve to open and refill the fuel supply. When the fuel bowl reaches its maximum capacity the float ascends to shut off the needle valve which stops the fuel flow to maintain proper engine operation. This part enables accurate fuel regulation which results in consistent engine operation and efficient fuel consumption and reliable starting.
