Guys, I've read many of the articles here and watched many of the youtube videos on the 2511. It seems that a ton of people suggest the muffler mod, removing the limiter on the carb, and advancing the timing. I'm comfortable with doing the muffler mod and removing the limiter. I'm less confident in advancing the timing, seems like that is broken if you do too much filing. I'm picking up my 2511 today and I'm wondering if I should mess with it at all. I could only get it with a 14" bar which is disappointing, I'd prefer a 10, which I'm sure I'll buy when I pick it up. What are your thoughts on modifying it at all? This saw will be for the endless job I have of cutting up limbs which are rarely over 6". I have big saws for other stuff.
