Just pulled the oversize pistons ( 20 thow. ) from my 1725. Notice they have a 4th groove just above the lower end of the piston skirt. Not an issue as I checked the rings I got from Classic Sunbeam, 4 rings supplied.
Just wondering why the 4th groove? Looks like a second oil ring.
Enquiring minds need to know.
