Many say a 24" bar is 70cc saw territory. We have other saws with 18" and 20" bars. So we decided to leave it 24" and see.
Saw runs it fine and oils plenty.
Stock chain is not so good, but we have pro chisel chains coming for it.
One week after this first run was filmed this saw was used to dismantle a large 40" 50'oak tree..and it pulled the 24" bar aggressively buried all the way!
With each tank of fuel it keeps getting better. After saw settled in from a couple tanks I richened up the low and high sides slightly- retuned and replaced carb limiters. Very nice saw. Will run with the professional Huskies and Stihl 60cc saws and has great build quality for a lower price.
Echo has stepped up their game on this new line of saws!
