PROBLEM TO BE SOLVED: To form a pulse passage capable of performing a stable transmittance of a pressure pulse into a pulse feeding hole of a carburetor at an engine work machine in which a resilient tubular member is arranged between an engine and a diaphragm-type carburetor.SOLUTION: A carburetor 10 at an engine work machine is fixed to an engine through a tubular member 20 and a carburetor bracket 30. The carburetor 10 has a pulse feeding hole 11 for feeding a pressure pulse at an abutment surface of the tubular member 20 against a flange part 22. Then, a pulse passage 70 for feeding the pressure pulse such as a pulsation of pressure in a crank chamber to the pulse feeding hole 11 is formed to pass through the flange part 22 of the tubular member 20 and the carburetor bracket 30.SELECTED DRAWING: Figure 3 |
