I have been given a 120NC new in the box. I am getting ready to start running the engine. What type of break in should I do. The manual tells you to run a tank of fuel very rich and then fly it rich. Alot of folks on the net are saying just mount the engine, set it rich and fly it. They say that running a tank on the ground does not provide proper cooling and is bad for the engine. Thanks for your response in advance.

I prefer to run any engine for about 1/2 hour minimum on the bench prior to installing in the aircraft. I guess this goes back to the days when you had to do this or the engines would sieze up in flight. Lots of our customers don't do this and have good luck just installing and flying, but running a couple tanks on the ground will allow you to get the settings right. I recommend it if you can.
