it could well be that the grease or oil on the side of the piston has
dried and has become sticky goo. just clean well with white spirit ans
apply a thin layer of thin oil. adjusting the valve hole should only be
caried out starting the carriage from the far end.
An alignment problem between the piston and the cylinder could also be
the problem. are the ball bearings of the carriage free running?

I can't remember if you should oil or grease the cylinder too, I am not at home to check what I did. Careful not to make the resistance too low either, it needs to be not too high or too low.

There is a mechanism, similar as a piston and a cylinder, which acts as a "bumper" or stopper. My problem is that this stopper, while not showing any signs of usage, seems too tight. If the carriage is all the way to the right, the spring will be strong enough to overcome the "too tight stopper". But if only a few words were typed followed by CR, the force is not strong enough to bring the carriage to its left home-position. Of course I could take down some of the piston's diameter to overcome the problem. But this doesn't seem right.
