Hi all,
Santa Claus (disguised as the Fed-Ex man) delivered a shiny new O.S. 25fx motor to my house on christmas eve. I read through the user's manual, and the break-in routine seemed fairly simple (probably deceptively so) -- mount the engine in the airplane, set your needle at some default setting, and crank it up. Run for one minute in four-cycle mode, then alternate 4 and 2 cycling for 10 seconds each until you run the tank dry. At that point they say just set it rich but 2-cycling, and fly her 3 or 4 flights before starting to gradually lean it out over the next 10 or 15 flights.

Is it really that simple or are there any gotcha's associated with this engine?

thanks!
