ABSTRACT:
In a two cycle internal combustion engine (80) comprising three cylinders (22, 24, 26) vertically in-line, a single intake manifold (82) services all three of the cylinders, and a single fuel delivery device (84), such as a carburetor, on the manifold delivers fuel to each of the cylinders. Location and orientation of the three reed block openings (90, 92, 94) relative to each other and relative to the throttle bore (128) provide desired fuel distribution. Manifold structure, including internal dams (142, 146) and a deflector plate (138), prevents an overly rich fuel mixture in the lower cylinder (26) at idle, and prevents an overly rich fuel mixture in the upper cylinder (22) at running speeds above idle.
