Title: Timing and throttle linkage

Abstract

This patent describes a timing throttle control for a spark ignition internal combustion engine having a fuel/air mixing device and a spark timing device. The control comprises a first pivot on the engine, a first lever mounted on the pivot and including a cam slot having a first portion which has a substantially uniform radius about the pivot and a second portion which has a non-constant radii about the first pivot. 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.
