I have a saito .65 and it runs great. I have it proped at 11x 7.5 and tach it to 10K. the 11x 7.5 is a very good prop for this motor. I might try a 12x6 or 12x7 some day, 13x7 might be alright not sure about that though.

I think I would prop it so that you can get above 10k with the tach, but don't go over 11k and then richen it back to 10k.

I don't count the turns unless I am starting over again and then I set it rich to start and use the tach to finish setting it at full RPM's. I have the plane secured very well when I do this.

I never lean any of my saito to a lean setting, I always use a tach and the right prop for the motor.

One other thing, not sure any one said this but the valves need to be set before, during and after break in. Once the engine is broke in, they very seldom need the valves set. I went and got the book on it and it says to set the valves between .002 and .004. (.03mm to .10 mm). Its important to have the valves set properly.
