True, my 5000 Echo has a big block in it, and a 22 inch chip throwing chain and bar.I went all Husqvarna as yard equipment died. Also exclusively use ethanol free (real) pump gas.
Like most brands ... until you get up into the "real" category of use (20" plus bar... high cc engines) the build quality just sucks
Johnson Red is the work horse in our are along with Echo .
