.65LA preset for airbleed
Our youth flying program recently had a plane donated that was equiped with an OS .65LA. We don't know the history of the engine, but it seems quite new (good compression, turns smoothly), but we haven't been able to get it to run smoothly. It seems to be running very rich on the low end (lots of smoke, loads up) even though our engine "guru" opened the airbleed fully. I am taking the carb apart today and cleaning it completely to preclude blockage, but I need to know where to preset the bleed screw when I reassemble it. I'm anxious for an answer as we intend to pass this plane to a very deserving student ASAP. Thanks in advance for any assistance.
