Abstract
A carburetor for a stratified charge two cycle engine with a choke bore, venturi, and throttle bore configuration matching an irregularly shaped choke valve. The trailing and leading edges of the choke and throttle valves, respectively, preferably overlap during wide open throttle operation to separate a single intake passage bore into an air intake passage above the choke and throttle valves and an air/fuel intake passage below the choke and throttle valves. The choke valve is preferably bent to minimize operational rotation and limit fuel spit back.
