no rep on upright

[wimblees at aol.com]

I installed a set of new hammer return springs on a Steinway console several weeks ago. The touch is on the heavy side, but not unplayable.?Even though everything works "right", on soft blows, the jack isn't going back under.?The keys are eased, the wippens and not sluggish, the hammer flanges?are not tight, and the jacks return when the keys comes up all the way, and? But on a medium fast repetition,?the jack doesn't come back under, and the hammer?butt gets caught on the back check.??Would weakening the return springs help this? Or is there something else I should be looking for.
