Abstract
An automatic engine control circuit and clutch actuating mechanism includes a primary timer which defines an off time and on time and a starting circuit that includes a second timer mechanism that determines the number of times the engine is cranked the duration in each starting crank. The engine control circuit also has a warm up timer that provides for an engine warm up period before a clutch actuating circuit is actuated to engage a clutch. The clutch actuating mechanism has a shaft with adjustable spring clips that flip limit switches in the clutch actuating circuit. A supplemental timer is operatively connected to the primary timer to allow for warm up periods without engagement of the clutch when the primary timer is in its off mode. Other safety sensors are operatively connected within the circuit to disable the engine if any unsatisfactory conditions are sensed by the circuit.
