Man I sat here and thought about that question and I really Dont have an answer because so much is going on. I could sit at my bench and I have sat at my bench with a scribe pointing out what I’m trying to get the air to do. But to explain it with words I can’t. Even now I have to think about where the air is heading. Common wall cylinder wall, pushrod side, center of cylinder. Sorry that’s not a lot of help.
