In any case for engine break-in I recommend you to do it with a small prop and low pitch (with the Rossi, I used 10X4)

A 12x7 will likely be too much prop for that engine. I would start with a 10x7 or 10x6 then move up as required to get into the "sweet" spot for your engine after it has some run time on it.
