I my experience, your extra partials come from an imbalance in the reed. Usually the high partials appear on high Bb-C, and imply that the reed is not vibrating as a unit, but as in parts. Usually this comes from an extra long tip or too thin of a tip, followed by too thick of a heart which stops the vibrations from traveling backward to the windows.
My best suggestion to try would be to:
1. Leave a little more in the center of the tip
2. If the tip is over 4mm long, clip it (measured from the bottom corners, not the middle)
3. Lightly dust in the heart just at the top (where the line between the tip and the heart is) by the rails on the side (don't scrape the rails or the spine). This helps the vibrations travel backwards more.
4. If all of this doesn't help, check the width of your rails, and the width of your spine as they might be too wide.
Hope this helps.
