ABSTRACT:
A carburetor of the slide and pin type having a throttle slide mounted in grooves on opposite sides of the throat and carrying a pin extending into a fuel discharge nozzle tube. The control edge of the slide has a concave recess which, together with the confronting surface of the carburetor throat defines the air passage surrounding the pin and concentrates the flow of air directly over and past the pin in such a way as to thoroughly atomize the fuel and distribute it uniformly in the airstream. Another feature of the invention is a choke arrangement comprising a longitudinal air passage bypassing the throttle slide and leading to a fuel choke valve and a cross passage into the downstream portion of the carburetor throat. The air flow through this passage will draw fuel up through the valve.
