Try pulling the action out just a mm or two. The damper lever could be clicking on the step at the back of the key. Also sight down and make sure the levers are on the proper spot on the keyend. It could be rubbing against the side of the next key. Space the one or two damper levers out of align or replace the felt on the left keyframe stop. Stepping on the unicorda pedal slightly will tell you if it's that.
