If it happens that your instructor did not give any advice regarding a break in procedure, then your instructor failed teaching you the right way.

Even if your engine will be fine (I hope so), a correct break in procedure is a must for many reasons, but I will suggest only one which is the one where your instructor failed.

A break in procedure leads to the owner of a particular engine to know how it should perform. Adjustments of the needle valves, temperature range of operation and deduct when your engine is completely reliable are just a few reasons.

I have seen many engines destroyed just because the user did not get aware of a break in procedure, the break in procedure is a relationship between the engine and the owner, this procedure tells the owner many things like the best prop and the best mixture, (What your engine likes and dislikes) many people override this procedure maybe for time consuming or lack of interest or knowledge.

With the exception of the evolution engines I have not seen until now any engine's owners manual which skip the break in procedure.

Even that the technology of these days where the tolerances in machinery are very tight, they do always recommend a break in period, minimal if you want but at last there is the recommendation "Break in".

When some new modelers have issues with their engines, they just can't figure out what is the problem, just because they do not have that relationship with their engines.

I also have read about the evolution engines and a short period of brake in and the gain of a bit amount of revs.
Sorry for this long post.
