Pulling the prop through wipes oil off the cylinder walls, lifters and cam lobes and also squeezes it out of the bearing clearance areas. What little oil that may be pumped back in is not significant. I prefer to leave the engine in exactly the position it last stopped until it is to be run again. And then, I prefer to run it long enough to get completely up to temperature and boil off any water that may have condensed into the oil. So, I guess you can guess where I stand on ground running... I've taken engines apart that have been sitting untouched for years and there is always plenty of oil in the bearings to survive a start. However, if you feel strongly, wait until the next time you're going to run it, and then pull it through 20 blades or so right before you start it. Or, do what ever you think is best...
