I was just curious how you guys broke your new saws in. From the sounds of it just set it a little rich and run it for a few thanks then lean it out a little....
To seat rings, which is all you are really doing in this break in procedure, the best way is to let saw warm up, set low and high jets, and then put it into some wood and cut wide open throttle with the saw loaded.
Im not saying peak revs, then drop it in, but what your looking to do is provide full cylinder pressure to seat the rings, so mid rpm, let it start cutting, then 5-8 cuts at full throttle with the saw loaded and keeping rpm around 9500.
Here I am thinking of a 16-20" log size to cut with a 20" bar as an example.
I use 32:1 Castrol 2T, and tune saw to 4 stroke out of the cut and double check with tach etc, just to add flames to the oil threads, but seriously, if you have just installed a new piston and rings, I assume you have assembled it with 2 stroke oil on the piston and rings, and some on the bearings whilst you had access to them.
there is enough residual oil there to take care of lubrication whilst you seat your rings, if you have already measured piston cylinder skirt clearance and squish etc, your good to go.
Avoid unloaded full throttle for at least a tank, unless you really have to test or set max rpm.
