Daniel, Like Terry said, decrease hammer blow distance. Then your problems (bobbling hammers/heavy touch) are probably due to too-strong hammer and/or damper springs...and it also could be too-soon damper lift. Also checking the height of the balance hole with a balance hole reamer would be in order. OK, check for too-tight balance holes and bushings, too.
