Yes, I have been there for run in my OS engine two week ago, but I don’t re member who you are. Anyway, I went ACO yesterday to run in that engine again, unfortunately, same result as many C Hing. And many C Hing seen what I did yesterday, I sure I did well in the run in procedure. No overheat, the engine reach the optimum before running on track, no full speed. But………………same result.
