        To the cylinder base. I went out and looked at a set of liners I
have left over from my rebuild. There is no lip between the part of the liner
that extends into the crankcase and the groove for the oil ring as I had
previously thought. There differently is a groove there. I used a dental pick
that had a 90 degree bend about 1/2" from the end to scoop the oring out of
the groove. You can carefully follow the sleeve up to the base of the
cylinder and you should hit rubber...

        After looking at the piston, the seat is just up the sleeve so just
pushing the liner down into the case should seat the oring - you don't have
to spend the hour or so lying on your back as I did ;)
