Kind Code:
U
Abstract:
An apparatus for controlling a carburetor of a combustion engine includes: a throttle-opening detector switch for detecting that a throttle valve of the carburetor is opened within a predetermined degree of throttle opening; an idle-up mechanism for making the throttle valve perform an idling-up operation; a fuel-cut mechanism for cutting a slow speed fuel supply of the carburetor; and a control unit adapted to allow the idle-up mechanism to perform the idling-up operation under a predetermined load applied to the engine and allow the fuel-cut mechanism to cut the slow speed fuel supply at a reduced speed of the engine when the throttle-opening detector switch detects that the throttle valve of the carburetor is within the predetermined degree of throttle opening. The control unit also includes an arrangement responsive to detection that the throttle valve is not within the predetermined range for inhibiting the idle-up mechanism.
