I've done a couple of searches on here for some information on engine break-in for control lines, but didn't get any hits in the control line forums. I'm a bit new to this and just finished putting together the hangar 9 pt-19, and have a powerful urge to fire it up. I figure that these engines have some sort of break-in procedure of some sort, right? Do you just run a tank or two through it? Do you start it out a bit rich and then lean it out after a couple tanks? Any help is greatly appreciated.
