valve problem

[newball]

Sometimes the valve (i think it is the valve, in the right tube if you look at the marker from the back) just opens and the air just blows out the breach/barrel.

I can fix it by turning in the screw on the front of my evolve kit but now it is all they way in.

Any ideas on how to fix this?

could be that your valve stem cup seal is worn. check it then talk to me.

Just took it out. It is hard to tell if it is worn but I think it looks ok.

Edit: Found the problem. The little spring in the evovle cap was broken/collapsed.

Where can i get a new one?
