Jon, thank you for the kind words, but he is correct, I can be a real asshole... and it all boils down to the way someone treats me... our buddy Al, decided to jump up and down throwing out insults over disagreeing on how the cooling system works, instead of actually trying to discuss it... I even let it slide at first, but if you are an asshole to me enough, I'll return it back, sometimes many times over... at this point, and it's always subject to change based on someone's behavior, Al should hope that if he's ever in need of help again, that someone else offers to help, because I won't... I'm actually shocked at his initial questions simplicity, considering the eventual admission that he is an air-cooled engine, all knowing, guru...
