An internal combustion engine comprising a crankcase adapted to rotatably support a crankshaft having an axis, the crankcase defining a plurality of crankcase chambers and including a generally flat manifold mounting surface including therein a first series of inlet openings aligned in the direction of the crankshaft axis, and a second series of inlet openings aligned in the direction of the crankshaft axis, the first and second series being laterally offset with respect to the direction of the crankshaft axis, and each of the inlet openings of the first and second series being respectively adapted to feed air to one of the crankcase chambers and having a minor dimension parallel to the crankshaft axis, a major dimension transverse to the crankshaft axis, and a portion overlapping the inlet openings of the other of the first and second series.
A carburetor comprising a throttle body section adapted to be mounted on a mounting surface of an intake manifold and having a first end including a flat surface abutting the mounting surface, an opposite second end including a generally flat mounting surface, and a first portion of an air passage extending between said first end surface and said second end mounting surface and adapted to communicate with an intake manifold intake opening, a plastic venturi section mounted on said mounting surface of said throttle body section and including a second portion of said air passage, and a generally horizontal, downwardly facing flat mounting surface, a generally cup-shaped, plastic float bowl section mounted on said mounting surface of said venturi section and including an upper end forming a generally flat surface abutting said mounting surface of said venturi section, and a reservoir including a float, a throttle shaft rotatably mounted in said throttle body section and extending through said air passage first portion, a throttle plate mounted on said throttle shaft in said air passage first portion, a generally vertical nozzle mounted in said venturi section and having a first end communicating with said air passage second portion, and a second end extending beyond said mounting surface of said venturi section and into said reservoir in communication therewith, and a conduit communicating between said air passage first portion and said reservoir.
