Ok, well, women are funny like that.
But you're new here, so I'll reiterate that I'm serious about the teardown and search for pockets of sand. Pictures from India indicate these engines are assembled on dirt floors, sometimes outside, under conditions that make it impossible for the assemblers to avoid contaminating the engine with dirt. Worse than that, however, is that the castings almost always contain remnants of casting sand. They aren't sandblasted, shot peened, or even washed with water after they are removed from the molds. And sometimes the assembler simply paints the inside of the crankcase right over pockets of casting sand.
You have a nice engine and a very little bit of sand can do an awful lot of damage. Spending a day or two stripping it down to bare castings, then scratching around inside with a screwdriver or pressure washing the inside, painting it with Rustoleum and then reassembling will assure you that your engine is clean.
