Hi all
As I am not sure yet whether the one-way valve in my engine breather on the Mighty Midget will lessen the oil consumption I bought a set of piston rings in case I need to change the barrel. However I'm not sure I will use them.
They are obviously Chinese and the top two compression rings seem identical with no markings on or different profile. The genuine rings have an N or R stamped on the upper face and have different profiles, top ring rounded, 2nd ring angled. The oil control ring rails are different, one is consistent thickness the other has a slight step in one face but no indication of which is the top rail and which is the bottom.
I am now reluctant to use them as if I get them in the wrong way around I might make the problem worse.
Any advice people?
