Abstract
An engine includes: a piston; a carburetor having a diaphragm fuel pump, the diaphragm fuel pump including a pump chamber configured to suck and discharge fuel and a diaphragm chamber to which a pressure to drive the pump chamber is applied; and a communicating passage configured to connect between the diaphragm chamber and a negative pressure part in which a negative pressure is created due to movement of the piston. A flowback prevention part is formed in the communicating passage to allow fluid to move only in on direction from the diaphragm chamber to the negative pressure part.
