ABSTRACT:
A throttle and timing control for a spark ignition internal combustion engine having a fuel/air mixing device and a spark timing device. A first lever is mounted on a pivot on the engine and includes a shaped cam slot a portion of which has a substantially uniform radius about said pivot and a portion of which has specifically non-constant radii about said pivot. A manual control is connected to the lever to actuate the lever about the pivot. A second pivot on the engine has an axis perpendicular to the axis of the first pivot and journals a second lever which controls the timing of the spark ignition. A spherical cam follower on the second lever engages and rolls in the cam slot so as to follow motion of the cam slot while turning the plane of movement 90.degree.. A third pivot on the engine is spaced from the other pivots and journals a lever operably connected to the fuel/air metering device. A link interconnects the first and third lever.
