The problem with running in is that there are so many methodes and most of them are basicly the same but starting a post like this you will get an endless topic and finally you do not know what to do....
Even the 1st tank idle (which I believe is very good) is still rejected by others.
My opinion, choose one of the methodes you will find on the net and use it or else use the one which is provided in he manual or on the site of the brands engine.
