I swear Echo can sit for two years with the dirt and mud on it and start right up on the second pull with the old fuel that was left in it. I have had many of both, being in the Landscaping business, and can tell you Stihl saws will not tolerate it. I'm keeping the Stihl saws I have, because I'm not wanting to spend the money to buy Echo new for that size (440 Mag and 064) but the Stihl yard tools I have will get replaced by Echo when they need. The Echo saws from 3400T, 352 (2) 490 and (2)590, I'm covered, except I think Im going to treat myself to a 271T, becasuse I want a very light saw to walk with. Almost forgot I do have a Stihl 170 with a dime tip to play at carving with, but, eh..... I suck at it.
