PURPOSE:To obtain high output power, by detecting the high-load operation of an engine to close a solenoid valve in an air bleed passage during said operation to supply a too thick mixture into the cylinder of the engine. CONSTITUTION:When a throttle valve 11 is almost fully opened, namely, high- load operation such as full-load operation is performed, a throttle switch 54 is turned off so that an analogue switch 52 is also turned off. Consequently, an electrical current to a solenoid 43 is cut off to close a valve port 37 in an air bleed passage 35 to feed a too thick mixture into an engine cylinder so that high output power is obtained. |
