Ok what started this was watching a youtube where he used glass and 3M 320 wetordry sandpaper and water. Said it would clog without water. So, I ordered a small qty of wetordry and its 220, 320, and a finer one as well.
As I mentioned, this is a mower engine and I wonder how tite the tolerance is before it affects reliability. I bet (just a guess) a few thousandths between high and low would be taken up by the gasket with no reduction in how long it stays sealed. But I dont really know, so I asked Google.
Kohler head flatness spec is .003" or less
I suppose I could clamp it into my Bridgeport and run the indicator over it but the BP is kinda beat and hasnt been gone through yet. Not sure how much deflection when moving the table around and it hasnt been trammed yet because I havent mastered that yet! Maybe this is the excuse to play with that a bit. Then the machine in theory could mill the head flat but I suspect the sandpaper on glass technique would allow the least loss of material...
