Need tips to improve my baroque flute embouchure.

[gerardo1000]

My usual C flute embouchure does not work with my new Aulos Stanesby Junior baroque flute. The sound that I get is weak, not full, with no color. While I was in the store to purchase the flute, the guy played it for me and he was able to get a warm full sound. Unfortunately the place is over one hundred miles from my home, so I can't go back there and ask for a few "embouchure lessons" ! Can any baroque flute player give me some tips to imrprove my embouchure ? This would be much appreciated. Thanks !
