Some food for thought - simply running it at 2300 for a long time --is just the factory's way of saying "please don't burn it up."
a constant long, steady rpm is not a good way to break in any engine -I don't care who makes it.
leave the cowl off -and fly it around at different throttle settings on the smaller prop - a 25/26x10 for a few flights
the whole idea is to let the engine seat without excess load(heat.)
Once it gets limbered up- then run the 27x10 . I will go one step further on this - runn8ng it steady at 2300 CAN cause more problems in getting it all seated -than simply flying it at varying speeds on smaller prop and varying speed low -med- high.
WHY? simply put, you may never get the thing to operating temps and if you do the 2300 long run-- cowled - setting there at low speeds -- you can overheat it .
