My first weed-eater (an fs-85) lost all compression within a year. I thought, ok, so I got the odd lemon, figures... A comparable echo (the srm-260s) is still running now starting it's 4th season (thou it is getting harder to start but still). My part-time chainsaw (an 021 / now 210) which was used some but it's a part-time thing, cutting wood is a sideline... 4 years after I bought it, if I got a season's work done in that time, down to almost 90 psi and I had to buy another one. Has anyone else noticed this with Stihl stuff? The backpacks I've bought have never given me trouble (both stihls, one a br-420, the other a br-550). Yeah, it could be the fuel but the backpacks run on it and the echo does, too... So I dunno, maybe ... No problem out of the hedge trimmers. The edger is too new to tell but I don't want to think about this one. Just wondering ... I get tired of stuff crapping out right after the 'warranty' period (or the equivalent of one year's solid use).
