摘要：
PROBLEM TO BE SOLVED: To provide an engine working machine in which startability is improved by sucking a large amount of fuel into an engine when starting the engine.SOLUTION: An engine working machine 1 is operated by an engine 10 including a fuel tank 27, a carburetor 40 and a crankcase 14, and is provided with an exclusive additional fuel supply path (71) for supplying additional fuel to the interior of a crank chamber when starting the engine, and provided with a starting aid device 50 having a solenoid valve that opens/closes the fuel supply path. The solenoid valve incorporated into the starting aid device 50 is driven by electric power of a battery 80 by a control means mounted on a control circuit board 90, and opens/closes a path from the additional fuel supply path (71) to a fuel inlet hole formed in the crankcase 14. When starting the engine 10, the control means controls to open/close the solenoid valve at appropriate timing, and thereby, the fuel is directly injected into the inside of the crank chamber.
