You might try adding the thin lead rounds that you buy for Stannwoodising
hammers and insert in upright hammer butts. You dont need much more then 2
grams or so to make quite a difference in this kinda problem. Usually if the
action will almost return to rest, but not quite enough to avoid jack
misfiring.... there is a friction problem somewhere.
