ABSTRACT:
A two-stroke engine with external fuel mixture generation in a carburetor. The engine including a suction funnel having an interior disposed upstream of the carburetor. The engine further includes a tapered insert having a narrow end and a wide end disposed in an area of an inlet port of the suction funnel. The insert at least partially defines the interior of the suction funnel, and the insert tapers in a flow direction of air flow from the wide end to the narrow end. Accordingly, a diameter of the interior of the suction funnel adjacent to the narrow end of the insert is substantially larger when compared to the narrow end of the insert.
