For 2 years now I have had my static line on the airspeed indicator unhooked due to very low airspeed reading when it was connected. In the early days I crawled all over the static lines looking for leaks. At my recent annual my mechanic hooked up the static and once again I was cruising at 80 and stalling at 30 indicated. After telling him that I would have to disconnect the static to get halfway accurate readings, he told me that the static side was being pressurized somehow. If the pitot is not pointing exactly straight air can blow into the static holes. Anyway, to make a long story long, he showed me his 1927 Rearwin which has the same exact pitot as the coupe except it came from the factory with a little disc with a set screw just before the static holes. This forces the air around the static holes. I picked up a 1/2 "shaft collar,drilled it out to 9/16 and slipped it on the pitot. Guess what? It works! My indicated speeds are now by the book. After being frustrated for 2 years it is amazing how simple the fix can be. Jack r
