Marine propulsion device with spark timing and fuel supply control mechanism
An engine is described comprising an engine block, a spark timing mechanism operable between a minimum spark advance setting and a maximum spark advance setting, a fuel supply mechanism operable between an idle setting and a full speed setting, a control lever supported by the engine block for movement between an idle position, a full speed position, a first intermediate position between the idle position and the full speed position, and a second intermediate position between the first intermediate position and the full speed position, means for displacing the fuel supply mechanism from the idle setting to the full speed setting in response to movement of the control lever from the idle position to the full speed position, and spark timing control means for permitting movement of the control lever from the idle position to the first intermediate position without displacing the spark timing mechanism from the minimum spark advance setting, for displacing the spark timing mechanism from the minimum spark advance setting to the maximum spark advance setting in response to movement of the control lever from the first intermediate position to the second intermediate position, and for displacing the spark timing mechanism from the maximum spark advance setting toward the minimum spark advance setting in response to movement of the control lever fro the second intermediate position to the full speed position.
