Hi Bax,

Just an update. I received the new piston/sleeve assembly yesterday and compared it to my original one. There is some peeling on the original sleeve on the outside of the ports. Also, the piston is damaged as such as it goes all the way to the upper lip without alot of resistance. I can't imagine how this happened, since both myself and my Instructor are very meticulous when we set the needles for flight. Anyhow, I hope this takes care of the problem. I'll keep you informed.
