Use Again - after realignment.Note the off-center position of the internal springs with respect to the outside spring. This can cause governor instability, which results in surging. Rotate the springs on their seat so that the inner springs are aligned (centered) with respect to the outer spring. Remove sharp edges (A) from the inside diameter of the flat surface on the springs to ensure springs seat properly.
