Zusammenfassung: | PURPOSE:To supply proper mixture in the range from idle speed to low one by providing an air path for low speed having one end opened downstream of a Venturi-tube of a carbureter and the other end opened to a position of a throttle valve opening a little more than that in idling. CONSTITUTION:A hole 8 downstream of a Venturi-tube 3 of a carbureter 1 communicates through a adjusting screw 10 and a path 7 to a hole 9 opened to a position of a throttle valve 4 opening a little more than that in idling. Thus, in the idling when the throttle valve 4 is closed, fuel set by the adjusting screw as usual is supplied. Since the hole 9 is located in the throttle valve opening position when the throtle valve 4 is a little opened in low speed, only an amount of air set by the adjusting screw is supplied from the hole 8. Thus, idling and low speed fuel are both maintained properly. |
