On my '73 Turbo Aztec, the Oxygem bottle was replaced when I bought the airplane. It worked fine the first three or four times I used it. Then I noticed that when I pushed the control knob down after use, it would work it's way back up by itself turning the oxygen on. Mechanic looked at it and can't seem to find any problems. He says that there is no spring or any catch mechanism to hole it in the off position. Any ideas?
