Full fine below 15'' of MAP on final, use full power for the go around, not climb power, it is just like a take off, just a little higher to start with.
There are a lot of pilots who read this and may take that to mean you use full power on the go around all the time.
Would this apply to all piston engine airplanes and all go arounds?
A go around is far different than a take off as you start the take off from zero speed, whereas a go around is commensed from a safe flying speed.
I can think of a few airplanes I wouldn't use that method of going around power wise in.
