The old school method involves running rich for the first few tanks and gradually building up the temps.Thishttp://www.rbmods.net/enginetempering.php explains why the old method is bad and explains the method most people are using now which is heat cycling.(i've heard all sorts of wacky methods but these are the most common and heat cycling is best)

I used this method on my sirio and prefer it,although it can be hard to get it up to temp quickly without feeling like you're abusing the new engine.That's why a heat gun or hair dryer is good to heat the engine before you start it so it's not so tight to reduce the risk of a failure.

Always let it cool with the piston at the bottom(BDC).

Also,i think it's best to use the same fuel and plug during break in that you intend to run,the link says to use MC59 plug and 30% nitro but i use mc9 and o'donnel 25% race fuel and it runs like a champ.

I wasn't able to get the temps up at the short 2-3min intervals but i didn't worry about it,i kept heat cycling up to 1 gallon but at 1 tank intervals(actually i still let it cool at BDC),big LST tanks though,maybe 2 tanks for the Revo.Do the short intervals for the first few tanks though.
