Abstract
PURPOSE:To adequately control air-fuel ratio of a mixture, by opening an air bleed control valve at high temperature start operation when detected temperature of a carburetor temperature sensor rises to at least prescribed temperature. CONSTITUTION:A low speed fuel passage 20 is communicated to a passage 26, opened in the vicinity of a slow port 18 in the downstream, and said passage 26 is opened with its upstream side port to the atmosphere and intermediately provided with a slow air bleed control valve 28. If a starter switch 38 is turned on, an input circuit 36 is in an input state, further a temperature sensing switch 44 is closed only wgen an engine is at high temperature, and an input circuit 42 is also in an input state, then a control circuit 34 outputs a control signal to open the slow air bleed control valve 28. In this way, air flows into the passage 26, and a lean mixture is fed from the slow port 18. However, rich fuel evaporated in a carburetor or intake pipe is mixed, and an adequate mixture can be fed as a whole.
