In addition to the Lycoming article above, work very hard to minimize ground run. Next time I have to do a break-in, I'd skip all ground run up, pull the plane to the end of the runway and just go. Preheat the oil if possible. If you're at a controlled field, call the tower and see if you can use a tug to get you to the runway. I may be a little overboard with minimizing the ground run, but glazed cylinders *are* a real drag. BTDT.
