Hey guys. Brand new member here. (And fairly inexperienced chainsaw user, too, as you will soon learn by my newb question.) I recently bought a echo cs 800p for chainsaw milling and noticed there is a thin metal x shaped piece on the front of the muffler (held on by hex screws) that covers 2 holes. My smaller saw has similar 2 holes on front of muffler but they are uncovered. Can someone explain to me the purpose of the part that covers up what I assume to be ports on the front of the muffler. Why its there, does it need to be there, will I be better served to remove it, etc. Sorry if this a dumb question I have a (VERY) limited mechanical knowledge of chainsaw. Thanks in advance guys.
