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
