"i mean all were doing here is seating the rings......"

This statement could not be more wrong. It never fails to amaze me that people spend hundreds of dollars on engines, many engines, and then proceed to destroy them by following some misguided internet raving on engine break in.

Forget most of what is posted on these forums. For the cost of less than a couple of gallons of fuel there are two books available written by acknowledged experts. "Model Four Stroke Engines" is written by Peter Chinn. "Two Stroke Glow Engines, for r/c aircraft" is written by David Gierke. Both books are published by Model Airplane News.

Instead of wasting money on fuel by the "Slobbering Rich" break in method, buy the books. Then read, mark, learn and inwardly digest. Stop destroying engines before they even get into the airplane.
