I am getting ready to install some nice new 62.5mm Venolia pistons into an Abarth 750 block and they shipped with Deves rings.
Anyone have any tips for me? Yes I have read this. This is also what venolia told me to do when I called them

My problem seems to be that the two rails and oil ring do not compress the expander ring at all so they just fall out of alignment before I can even put the piston in the ring compressor.
This is pretty annoying.
