Abstract
Systems and methods for draining fuel from a carburetor of a combustion engine can include a first control valve in communication between a fuel source and a fuel chamber of a carburetor and a second control valve in communication between the fuel chamber of the carburetor and a drain reservoir. The first and second control valves can be coupled and operable such that, upon disengagement of the engine, the first control valve can be closed to block a supply of fuel to the fuel chamber, and the second control valve can be opened to connect the drain reservoir to the fuel chamber, which can operate to draw liquid fuel from the fuel chamber into the drain reservoir. The fuel can then be moved from the drain reservoir into a fuel storage tank, where it can be stored until needed by the carburetor.
