yeah thrust washer is in place, I actually forgot to put it on with my first Evo motor and it won't turn over after the prop is tightened. The flywheel hits the case. It has over 100 flights on it and it just started doing it about maybe 20 flights ago. Gonna tear it down and see what I can find out. Very strange though indeed. Maybe I'll try shimming it too see if that helps, I am using 30% nitro as I do in all my motors that allow it and some require it with the higher nitro content. We'll see
