lol@ Mike, careful someone doesn't take a shot at your puppy, heh heh.
Chris, that sucks. The first thing I did with my new motor was pull the head/jug, it had quite a few metal shavings/filings all over it
Gotta check'em. 13hp would be crazy fast
I spent a couple hours in the sun polishing up a mottled/pitted intake. It was the style without the welded bend and flange, but looked like crap. Came out good. Gotta find the buffing wheel for Mr.Dremel and take some toothpaste to it, should be like a mirror(or close enough).
Top left is what it looked like,(eww), top right is before the 600 wetsand.
