I have a Kalison with the four pistons vented out of the bottom. When I move the valve slides in and out with speed, I hear a kind of air-swishing sound coming from the valves. I think valves/slides work fine, but my repair guy heard the sound and said that the valves weren't vented correctly. Any comments?
