For all the 550xp owners. I finally ran my little 550xp saturday and noticed it had a slight stumble when accelerating off of idle. It never got worse or better the longer I ran it. I remember reading something about this issue with them. So sunday I tore into it. I took the intake horn that air filter sits on off. While the carburetor is still on the saw and you are facing the carburetor, there is a brass plug. I drilled the brass plug out and there is a air adjustment screw in there. I backed it out 1/4 turn and tried it. I ran for 20-30 min and the stumble is gone. So I just thought I would share this with everyone.

My saw stumbled a few times on the first few tanks of fuel. It's good now. Took a while for autotune to get it's act together.
But mine came with some kind of small rusty metal debris in the muffler, about 20 pieces total. You could here it when moving the saw around when shutoff, almost like a baby rattle. So the muffler was replaced under warranty. The parts didn't come out of the motor, must have been a manufacturing defect.
