A carburetor with a manual priming pump having an integrated fuel drain which provides both the engine manufacturer and end user with an easy way to drain fuel from a fuel chamber of the carburetor. The priming pump has a pump chamber defined by a resilient priming bulb. The pump chamber generally communicates between the fuel chamber and a fuel-and-air mixing passage of the carburetor body and is preferably positioned above the fuel chamber. The dual function of the manual priming pump, prime or drain, is switched by a valve with a rotatable selector member received between a seat and the resilient priming bulb of the pump. The selector member moves between a drain position and a priming position thus enabling draining of the fuel chamber or priming of the carburetor via successive manual depressions of the priming bulb.
