A control means is connected to the first lever to actuate the first lever about the first pivot, a second pivot on the engine in non-parallel relation to the first pivot. A second lever is mounted on the second pivot and operative to control the timing of the spark timing device, a spherical cam follower is mounted on the second lever and engaged with the cam slot. A third lever is mounted on the third pivot and operatively connected to the fuel/air mixing device. A link interconnects the first level and the third lever.
