You need to run it for 12 hours straight with low nitro - High oil fuel, while standing on one foot and swinging a chicken over your head.
Personally, I never go for all of that stuff. Run it very rich at half throttle for a tankfull, then lean it out but leave it a few clicks rich and fly it. After 3 or 4 flights, tweak it up and fly the heck out of it. Never had one fail yet (And I've been doing this for a while)
Hey Minn sorry to correct you but it's standing on your left foot with a "rooster", Chickens tend to shoot out eggs at the plane

I'd pay to see someone (try and) grab a rooster by the legs and swing it, ( I read about a guy trying that with a barn owl and when he finally let go it took part of his index finger with it)and 12 hours is plenty of time to bleed to death

cisco most people dont bother getting an engine to 4 stroke cause even OS only recommends it for 10 to 60 seconds and at intervals..its more important for an engine to reach operating temps than it is for it to 4 stroke because it is slobbering rich but the theories behind this will be argued till the end of time,,on my 1/2a engines , fire it up run it a little rich full throttle for 1 minute cut it off,let it fully cool, wait 5 minutes and do it again 4 or 5 times then go fly......
