I have one question for all the Iwata users here on this forum. When you take off the needle and nozzle cup and look at the nozzle you can see how the needle sticks out of it. When you press on the trigger the needle moves back. And now my question: when pulling back the needle does it move centered all the time or does it lean a bit to the sides of the nozzle? A picture might show it better:

The needle on the left moves back centered, and the needle on the right is a bit leaned to the side of the nozzle. It looks like there's some free space in the needle chamber inside of the airbrush and the needle has enough room to actually move crosswise, thus leaning to the left sometimes and leaning to the right when I release the trigger. When I move the trigger up and down the needle moves a bit inside and it touches one side of the nozzle when I press the trigger and the other side when I release the trigger. Is this normal?? It's a movement of around 0,1mm but you can see that the needle is not perfectly centered in the nozzle. I'm not sure what to think of it.
Thanks for any help,
Cheers,
