ABSTRACT:
In line carburetor (104) is mounted to a manifold (140) over the engine (800). The barrels of the carburetor deliver air/fuel suspensions to concentrated positions (152) of the manifold, with the concentrated positions being at opposite ends of the engine. The ports leading from the manifold to the runners are equally positioned about the concentrated positions (152) so that the runners are of substantially equal length and resistance, thereby providing more uniform delivery of the air/fuel suspension to the cylinders.
