Oil consumption seems to be pretty good at about 1 qt in 10 hours. Not doing any negative G yet. I stuck a camera in all 4 cylinders and they all 4 looked like the picture below. Any comments?

The last flight was not high power and I had kind of a long reduced thrust descent to landing. I don't know if this is normal in the break-in period. My CHT is doing well and oil consumption looks good. Still I have oil in the combustion chamber. Anyone?

Also with my aerobatic prop it is hard to run it at high pressure and not overspeed the prop.
