OS95 four stroke, anybody seen one?
Hello ; I have been admiring OS, engine ads, and I need a 90 to 115 size engine for my 90 Funtana. I had an os surpass 91 that I flew for nearly 6 years in one plane or another. It some how bent the push rods (maybe over revved a tiny bit)
After I straightened the pushrods it ran pretty good, but after about 6 tanks full it would somehow bend the pushrods again. I sold that engine because it looked perfect on hte outside, but kept bending those rods.
I wonder if OS changed the valve operating system because of the same problem I had, and that that was the best way of dealing with it.
anyhow; I'd like to hear something about that engine.
