ABSTRACT:
An exhaust timing controller for controlling an exhaust timing member in a two cycle engine including a control circuit for generating a control signal which actuates a mechanism for moving the exhaust timing member. The control circuit controls the member such that the member is drivable in a range from a fully open position to a fully closed position responsive to certain engine conditions including engine speed and rate of change of engine speed. A self cleaning cycle is provided which drives the exhaust timing member first to one position limit and then to the other.
