Abstract
A choke and throttle control arrangement for a small engine includes a base plate to which a pair of levers are pivotally joined. One includes a governor spring arm connected to the engine's speed governor, and the other is provided with an arm which serves as a choke actuator. A spring interconnects the two levers to permit them to rotate in unison at low engine speed in response to operator actuation of a throttle control handle. An adjustable stop member is positioned to interrupt the rotation of the governor spring arm when a selected less-than-maximum engine speed is reached. Further throttle control handle advancement permits the choke actuating arm to move to the closed choke position. As the throttle control handle is moved towards a low speed setting, the lever containing the choke actuating arm returns to the position at which the selected less-than-maximum speed was reached. Once reaching that position, both levers move together under the influence of the interconnecting spring as the engine speed is reduced.
