AHHH! DON'T DO IT!

The corrigated ring is supposed to be 'too big' When you install it with
the emds touching (NOT overlapped!) it looks like it will never fit. After
you put the two thin steel wiper rings on, it still looks too big, but whne
you squeeze with your ring compressor it will fit fine.

If it won't compress after you get the wiper rings in, check to see that
the ends have not overlapped.

This gadget forces the wiper rings out against the cylinder to scrape the
oil off when the piston goes down. If you fiddle with it, you will probably
end up burning more oil than you should..
