Review on High-Performance Carburetor with Air Filter for Polaris Sportsman 500 4X4 HO (2001-2005) by Larry Gaines

Fuel leak immediately when starting the device. These carburetors lack the plastic seal on the float needle valve that is supposed to keep the port closed. Without this gasket, fuel will fill the reservoir and overflow the chamber, spill out the overflow hole and leak throughout the engine, presenting a serious hazard when the engine is hot! Be careful as spilled fuel can ignite on hot surfaces.
