Abstract
A throttle and timing control for a spark ignition internal combustion engine having a fuel/air mixing device and a spark timing device. The control includes a pivot on the engine, a first lever mounted on said pivot and including a shaped cam slot a portion of which has a substantially uniform radius about the pivot. A control is connected to the lever to actuate the lever about the pivot. A second pivot on said engine spaced from but substantially parallel to the first pivot supports a second lever which has a cam follower engaged with the cam slot. A motion take-off connection on the second lever is spaced further from the second pivot than the follower so the motion imparted to the follower by movement of the cam plate is multiplied at the motion take-off point. A third pivot on the engine spaced from the first two pivots supports a third lever which is operatively connected to the timing control device. A link interconnects the first pivot and the fourth lever which is part of the throttle control.
