Somebody's talking crap here & it ain't the tree!
I find this with most new saws to some extent. On piece of the puzzle is the fact every saw is tune at the factory for the area they are being shipped. The fuel and possibly elevation is different here, but yes most new saws I've ran are set too lean from the factory do to the EPA.
Now get to work and make some chips.
Just about to head out with the 3120 and 42" bar so will make bulk chips and get some vid for the "Today's Job" thread
May even get the 261 into some of the smaller stuff for some mini chips
I'm not sure if the Aussie delivered 261's will be richer and less dolphin friendly but you can't assume anything nowadays.
