I seem to have picked up a habit from my father. Every time we watch a movie, I nitpick at all the little things that they got wrong, but ignore the huge things. For instance, My little sister was watching "the robinsons" on tv (it's a cartoon movie), and I had nothing better to do so I sat down and started talking about how nobody's hand could possibly fit around someone's waist. Meanwhile, they are in a flying time machine, going through paradox after paradox.
The little thing in all of this is the degree that it bugged my sister. Normal nitpicking would bug her, but the way I was doing it, nitpicking at the small things and ignoring the obvious ones, really got to her. Hahaha that made my day. I'm an awesome brother, aren't I? >
@Rubiksklube- Drill a second hole next to the nozzle on the cylinder head, opposite the original hole. Then take a piece of wood, drill a hole for the nozzle, and two holes to mimic the ones next to the nozzle. Use those holes for two nails, and use it as a wrench to take the cylinder head off. Springer shows how he made it here ((Clicky!) It's post #12).
