Hi,

Well the engine is new and freshly broke-in. I adjusted the air-bleed and the high speed the same way I did for other O.S. 2 strokes I have. The manual says the kit can use a .40 but I had a feeling it would be under-powered. I have an O.S. .46 La on a Tower Trainer 60, it highly under powered but still fly's great. The PC-9 would only start when it was inverted, then run kinna rough when we put it upright. I looked close at the main needle and it was below the fueltank. Today I will re-locate the main needle valve and set it above the tank, it will take some slight moding but I think this may be the problem. I also have 2 Perry Pumps if all else fails.

Thanks again!!
