Not sure about point two.
Maybe somebody who has or had the problem couldn confirm that...
My problem was that the bike did not want to start at all. Instead, the engine was making the noise described in the first post. Too bad I didn't think about recording the sound before starting the "how to" thread.
Sometimes, if I was lucky, the engine started, but generally it just made a lot of noise and it didn't want to turn over. It always starded when I kicked it, though.
