Yes it sounds like its a little too tight. Go clockwise just a wee little bit! Clock wise adds more play, just the opposite of American gear boxes.
Put a mark on the box and one on the Allen headed bolt as reference.
You might try swapping the the right side tires front to back as well, sometimes a radial tire takes a "set" and will lead the car to the right or left.
Its just more noticeable now with less play.
If the car returns to center quickly after making a 90 degree turn onto a side street then its probably OK.
Another item often overlooked is the steering linkage damper, it bolts to and runs parallel to the center link, looks like a skinny shock!
Most steering dampers are worn out and the car will tend to follow ruts in the road.
Just unbolt one end and try pushing it in then pulling it out, should have a fair amount of resistance, and new ones are not expensive.
Replacing it makes a world of difference in steering feel.
