No fair John! You know someone had to do it though. Don's a great builder and a college professor but internal combustion engines are a mystery to him. There aren't any secrets but if you haven't been exposed to the mechanical side of things you just plain don't know or understand what makes em work. As I love to say "it aint rockit science" (sp) I rebuilt my first lawnmower at ten, small block Chevy at 15. Oh what fun. Mom said she'd kill me if that lawnmower didn't run, I'm still here. lol
