Per the Kohler manual they supplied rings as STD, .003, .010. .020 and .030 oversize
Recently while talking with a "Sears" tractor collector about rebuilding engines he said that the Briggs and Kohler "STD rebuild kits on the market today all actually have -003 oversize rings in them.
That way if you engine has a little wear, but is still in standard spec these .003 oversize rings will take it close to back to new compression. Anyone have the straight answer?
Is this correct for Kohler replacement rings?
Is this correct for all aftermarket replacement rings?
