Lets talk piston rings; this 27hp kohler has 3, top middle and oil, the latter is a no brainer, the top 2 however....one is for the most part square cut and dull to dark metal finish, the other has chrome where it contacts the bore and appears to be double beveled, no other makings on either. 3 of us have looked at this under a lighted magnifying glass and the bevels are extremely had to tell. Instructions that came with the rings don't help as it shows a double bevel could go either place, set is genuine kohler and for multilabel applications. I should also mention, have the old style pistons and from what I could tell the ring number changed once before they went with the new style, that is the set I have.

Last question is case halves sealing, it had silicone, service manual also shows silicone but I do have a gasket in the set. If I use the gasket will it change the end play on the cam and crank? should I go with silicone? what kind? original was silver in color.
