I'm sorry you've got such a short attention span Dar...watch out or you'll become known as Dar the Goldfish

You might find this interesting though.. http://home.kabelfoon.nl/~fiorimet/Index.htm side bar "Running in" and then the third para.

For the rest who are interested, I've started running in the engine according to the "Go here or you'll ruin it!" thread. I'm using an APC 10x6 and it chugs along quite nicely at 13,000 with a head temp of 300F and a very occasional 4 stroke "miss". There's a very pronounced rise in revs when I pinch the fuel line to shut the engine down so it should be rich enough. The rise is more than the 500 rev below peak as in post #7 of that thread so obviously it must be OK.

But could Dar explain to me, a rank beginner, how you find 500 below peak if it could damage the engine by peaking it in the first place?

I must admit the head temp of 300F worries me but what do I know? I'm just doing what I'm told to do
