Give us your proven run in methods for .21 Novarossi engines.
I have been using Swauger method on my Ninja/GRP motors with great success.
I have now bought a Novarossi 359 which I want to run in on the bench prop.

I saw a post on rb products forum about a new break in procedure. I used it and it works awsome. I made a setup to fit in a gallon jug that I can run the engine nonstop. Go to rb's website and read about it.
The most important thing with any break in method is to make sure you get the motor up to temperature. If you break it in cold you are ruining it. If you use a bench put a shroud of some sort around the head to help it get hot. Aluminum foil seems to work.
I still prefer to do it in the car.
