Dual acting - double breakover throttle lever

A failure-proof dual acting - double breakover throttle lever is provided to maintain control over engine throttling in the event of failure of the vehicle throttle control or related structures. The throttle lever assembly (50) is operatively positioned between an operator-actuated throttle control and the engine fuel supply system. A throttle link lever (56) mounted for pivotal movement relative to the throttle lever (54) is actuated by the throttle control to cause the throttle lever to rotate a throttle shaft (52) between preset full throttle and idle positions. The throttle lever (54) and the link lever (56) include integrally formed tabs (55, 57) which hold a coiled torsion spring (70) positioned to resist breakover, thereby normally maintaining the assembly in an axially aligned operating position. Double breakover stops (82, 84) formed integrally on the link lever (56, 74) are provided to limit the breakover travel of the link lever to predetermined limits by positively contacting the throttle shaft in the event that the breakover mechanism is activated.
