The Echos just work. I gave this 490 to my brother in law a couple of weeks ago to replace his 5020 poulan. He loves it. I run pretty much all echo saws.
Nice. Sold my 2511T after getting the 2511 P. I put Echo's 3/8 lp .043 gauge narrow kerf bar and chain set up on it. No chattering like the factory setup.
Somewhere I've got a picture of the 7910 with a 32 looking like a toy on the big oak you helped me with. Have to see if I can find it.
