As I said, these engines are not "run in". This is directly from Hobbico's website

Notice it says "factory-set". This is a very common misconception about this plane. Many think this means that they are "broke-in" at the factory, but this is not true. What they do when they assemble the plane is simply start the engine and tune it, this is where they are "factory set". They then shut down the engine and install the needle limiter. What happens is that a lot of people discover that when they start the engine in a different climate than the factory is was set at (changes in humidity, temperature, and elevation) they are unable to adjust the plane because of the limiter. The pilot should remove the limiter and adjust the engine and reinstall the limiter. I recommend that students follow the breakin procedure for the engine as called for in the manual. Remove the limiter and break in the engine. Then set your needle and install the limiter if you wish. IMHO you're better off just removing the limiter and learning to adjust the needle yourself. Murphy's laws on technology state "if you foolproof a system only a fool will use it".
You could start the engine and fly it if you want. but if you want my opinion I'd recommend that the engine be broken in properly. You'll be rewarded with a reliable long lasting engine if you do as the manual calls for. But read through the manuals, or Hobbico's literature and website, and nowhere will you find that the engine is "broken-in" at the factory.
