ABSTRACT:
An air-cooled engine having a vertical crankshaft and a horizontal cylinder. The cylinder is cast aluminum alloy and has the intake and exhaust valves located next to one another on one side of the cylinder, with the carburetor located on the other side of the cylinder. An intake cross-passageway integrally cast in part with the cylinder passes under the piston bore to connect the intake valve to the carburetor. For casting purposes, the lower side of the passageway is open in the cylinder casting to permit removal of the passageway casting core and forming an opening having side walls extending transverse to the piston bore extending from the passageway to the exterior of the cylinder. A cover having side walls corresponding to and lying adjacent the side walls of the opening is disposed in the opening. The cover has a curved inner surface corresponding to the curvature of the passageway.
