Abstract: An electronic fuel injection throttle body unit has a core body with two side components. The two side components each including a fuel delivery passage. Four air intake passages extending vertically through the throttle body. Valves are rotatable within the air intake passages. The valves being connected to valve shafts that rotate about respective valve shaft axes. The valve shaft axes and the fuel delivery passages are perpendicular to each other.

Abstract: A distributor is configured with an outer housing that has a first portion and a second portion. The first portion and the second portion are adjustable in angular orientation relative to each other. Movement of the second portion relative to the first portion changes ignition timing in the distributor. The movement can be caused by rotation of a thumbwheel such that ignition timing can be changed without mechanical tools. The first and second portions also can comprise visual or tactile markings such that ignition timing can be changed without a timing light. The outer housing can be used in multiple applications simply by changing a length of a shaft housing member that houses a distributor shaft and a gear that is mounted to the distributor shaft.

Abstract: A fuel injection unit is designed for replacement of existing carburetors. The fuel injection unit can be sized similarly to the existing carburetor. The fuel injection unit can have concealed fuel injectors. End caps can be provided that overlie the fuel injectors and that contain fuel line connections. The end caps provide an appearance of carburetor fuel bowls while generally concealing the fuel injectors and the associated fluid connections.
