Patent ID: 6896245

Claim:
A carburetor, including: a carburetor body having a scavenging air passage and an air intake passage formed therein; an air valve disposed in communication with the scavenging air passage and moveable between closed and open positions to control air flow through the scavenging air passage, and an air valve operating lever carried by the air valve for rotation with the air valve; a choke valve disposed in communication with the air intake passage and moveable between an open position permitting a substantially unrestricted fluid flow therethrough and a closed position restricting fluid flow through the air intake passage, and a choke valve lever carried by the choke valve for rotation with the choke valve; a throttle valve disposed in communication with the air intake passage and moveable between an idle position restricting fluid flow through the air intake passage and a wide open position permitting a substantially unrestricted fluid flow therethrough, and a throttle valve lever carried by the throttle valve shaft and coupled to the air valve operating lever by a lost motion coupling enabling limited movement of the throttle valve relative to the air valve during at least a portion of the movement of the throttle valve between its idle and wide open positions, said choke valve lever being arranged so that when the choke valve is closed the throttle valve can be moved away from its idle position while the air valve remains closed so that a rich fuel and air mixture can be delivered from the carburetor.
