Abstract

A carburetor including a carburetor tor body (22) having a throat (24) extending from an intake (26) to a discharge (28), and a fuel nozzle (32) positioned within the throat and including an upstream orifice facing substantially upstream and a downstream orifice facing substantially downstream. A
surface area of the upstream orifice is smaller than a surface area of the downstream orifice. If more than one orifice is provided on each side, a combined surface area of all upstream orifices is less than a combined surface area of all downstream orifices. The upstream orifice is positioned closer to the carburetor body than any of the downstream orifices.
The downstream orifice includes a plurality of downstream orifices that have an average position that is centered with respect to the throat.
