Well, the problem is solved, the thin oil helped but did not stop the leak. I took the retract apart removed the cylander and opened it up, oiled and cleaned the oring manualy, still , no joy [&o]. So i removed the o-ring and simply flipped it around 180.. This worked, the leak is totaly gone now. I dont know why flipping it would make a difference but it did.. If the leak ever comes back i will just go and get new orings at the hardware store..Now i can put the test flight on the plane.. Thanks Russ
