ABSTRACT:
A carburetor for an automotive internal combustion engine has primary and secondary barrels, each of which contains an air intake passage, a venturi and a throttle valve arranged in the air intake passage. The secondary throttle valve is adapted to open in response to the resultant of the primary and secondary venturi vacuums. The opening of the secondary throttle valve is, however, obstructed to suppress an unnecessarily rapid increase of engine speed.
