I know about the chirp/whistle, they all do it. My cousins WR does it, so I´m not concerned about it.
It´s the plate rattle that worries me. I did not see any problem with the seal nor excessive wear on the plate but i´ll replace it anyway.
The fuel screw is 2 1/2 turns out and will check for leaks later on. Will post the ffindings.
