Reed Valves
Rick-1 It depends what kind!
Some do have a valve but not in a reed configuration. The crankshaft is machined with an axial port down the center. It has an opening in line with the carb and acts as a rotating valve. Some 2 strokes have a series of reed valves and function precisely the way you are thinking. This inexpensive homelite motors have reeds. They work fine for what they are designed to do.
