I had the exact same issue with my EQ6. It ended up being a combination of the worm end float and the worm meshing (i.e. 1 & 2 in Peter's post).
Hours of tweaking these finally got it to the point where it takes <= 5 pulses in DEC to clear the backlash. Also keep in mind that having the float too tight can appear as backlash as well, as was the case in mine.
I've also had the set screw come loose on the RA axis after my belt mod. I was doing PE recording at the time and things didn't seem right; when I reviewed the PE curve it was really smooth, so that's one way to identify that. In my experience (sample size of 1 here) the amplitude of the PE will be about the same as it otherwise would, but it will appear much less noisy than usual.
