Wrist Pin Clips

I prefer the "wind-up" style clips . . . when installed correctly, they don't come out.  Always make sure you have a flat-end style wrist pin.  The end of the pin should be flat against the face of the clip.  verify that both edges of the clip are secure in the piston groove.  Due to age, I now use my new no-line bifocals and a lighted magnifier to make sure it's a go.
