good morning, I bought the co2 regulator mate but it doesn't work. the air comes out somewhere, I think from the seam under the bubble counter. it is not stable, even by tightening the joint the bubble counter can turn and move. if I keep my hand there it works but if I take it away it stops emitting bubbles. I also tried to open under the bubble counter where the spring is but the problem is the joint further down which is wobbly. plus I no longer know which direction the spring is right.
