Abstract: A timing sprocket for a camshaft is provided with a number of positioning holes equally spaced in a circle about its axis of rotation. A vernier plate connected to the camshaft is provided with alignment holes equally spaced in a corresponding circle as the circle of positioning holes but at a slightly greater or lesser angle. Alignment of a positioning hole and an alignment hole using a positioning pin permits incremental rotational adjustment of the sprocket wheel relative to the camshaft for angular increments equal to the difference between the angles of the positioning holes and the angles of the alignment holes.
