Abstract
An exhaust control valve assembly for a two-cycle engine includes a governor for moving an exhaust control valve in opening and closing directions to advance or retard a timing of opening of an exhuast port. The governor includes a governor spring for urging the exahust control valve in the closing direction. The governor spring exhibits a changing spring constant which increases as the exhaust control valve moves in the opening direction.
