To obtain satisfactory and stable operation by dealing with even sudden load variable without time delay, by automatically adjusting an opening degree of a solenoid valve before performing actual work after engine start and by providing a proper air-fuel ratio.
After an engine 7 is started, when being within a fuel flow rate adjustment rotating speed range applying a fixed load in a work rotating speed range of the engine 7 where a throttle valve 4 is opened for a fixed opening degree, a detected rotating speed is fed back with respect to a target rotating speed, a fuel flow rate is adjusted by controlling an opening degree of a solenoid valve 3 of a vaporizer 1 to control the detected rotating speed, and the valve opening degree is determined to achieve the target rotating speed. By operating at the determined valve opening degree, a combustion state of a fuel in the engine 7 is brought into best state.
