Is there a point to breaking in a gas engine on test stand or running the engine rich? Just wondering as I've been seeing quite a few threads lately of people running their gas engines as if they were glow engines. Running them for hours at a time at a constant rpm, that can't be good. Am I wrong? The way to do it is to still mount on the airplane peak it out then back it off 200 or so rpm and fly it, right? Just wondering if i missed something.

PSP Manufacturing makes one of the best I've seen. What you mount it to is up to you. No need to run a new gasser rich, just make sure that it has adaquate airflow so you don't cook it.

Best way is still to fly it. Those that have a need or like working on them use a stand for convenience and accessability.

Depends on what you are doing with it. I have a new Ralph converted G-62 on the way that I want to try a number of props and exhaust options on. To do that on a plane is a PITA, and you don't get quantitative numbers with the plane in the air. So a stand is way more convenient for me to do all that and get some running in done at the same time. But you don't NEED to break it in on a stand with a gasser. You can install it in the plane, run a couple of tanks through to set the needles and get a good transition, then go fly it. Nothing wrong with that at all.
