ABSTRACT:
A two stage carburetor for introduction of an air-fuel mixture into the crankcase of a two-stroke marine engine includes a carburetor body that defines a pair of throttle bores, one of which has a reduced cross-sectional area. The throttle bores deliver an air-fuel mixture to separate and distinct reed blocks having comparable cross-sectional areas.
