Abstract

A variable area venturi carburetor has a movable venturi wall with a fuel metering rod attached for cooperation with a fuel jet located near an opening in the fixed venturi wall portion, a bypass passage connected to the connecting chamber between the fuel jet and the wall opening siphoning off the fuel at closed positions of the throttle valve to prevent stumbling of the engine by fuel flowing into the main venturi and clogging the small clearance space between the throttle valve and induction passage wall.
