I have an older Saito 65, with an air bleed carb. It starts and idles fine, but when you take off, about 30 seconds into the flight, it dies. I'm getting a lot of practice with deadstick landings, but would rather not have this much practice. I have an OS F glow plug, using Cool Power 10 % fuel. I dont know if it has ever been properly maintained/adjusted, and don't know if that could be the problem.
