Default Rules for 2 stroke engine's break-in

Hi ya'll,

I always wanted to find out and ask what exactly are the rules for engine break-in. I have ordered JBA .56 through knoxhobbies, still haven't gotten any shipping confirmation yet but it's scheduled to be delivered this week. How do we break-in the engine?

1. Use the recommended props?
2. How many tanks need to run through?
3. How should we let the engine run? Full throttle, half or quarter and do we have to keep moving throttle full to lower up down over and over again or some time delay?
4. What is high speed and low speed needle and where is it located? is it the one that we turn to make the engine run lean or rich.
5. After succcessful break-in which size prop should be used and mostly engine should be run on rich side or lean side? pros and cons of rich & lean.
6. Last question does break-in apply to all the 2 Stroke engines same way.

Thanks in advance, though I asked a lot of question but I gotta do it for the first time so I want to be sure before I do anything. As I always used pre-broken-in engines or running engines.
