ABSTRACT:
Improved throttle and spark advance linkage is suitable for use in a marine drive, such as an outboard motor, having a throttle valve, a throttle operator with a cam follower for opening and closing the throttle valve, means for altering the ignition timing, and maximum and minimum spark advance stops. The linkage includes a spark advance lever pivotally mounted on the marine drive. The spark advance lever is coupled to the means for altering the ignition timing so that the timing is advanced and retarded responsive to the pivotal movement of the spark advance lever. The spark advance lever has means engaging the maximum and minimum spark advance stops for limiting the pivotal movement of the spark advance lever. A throttle lever is pivotally mounted on the marine drive coaxially with the spark advance lever. The spark advance lever and throttle lever have cams coacting with the cam follower on the throttle operator for opening and closing the throttle responsive to pivotal movement of the levers. A coil spring couples the spark advance lever to the throttle lever for obtaining common movement of both levers while permitting independent movement of the throttle lever when the spark advance lever engages one of the stops. The coil spring surrounds the pivot axes of the throttle lever and spark advance lever. The coil spring has ends engaging radially spaced projections on the spark advance lever and throttle lever to obtain the common movement. The resiliency of the spring permits the independent movement.
