I had a "defective" decompression valve on a brand-new CS-590. I went back to the Echo Dealer (not big box store) and told him it was not releasing and sticking. He didn't even want to see the saw, he just believed me. He ordered a new one, called me when it came in. When I went to pick it up, I told him I could install it if I had the torque value, but it was probably the same as the spark plug. Hit went in the back and came back with a torque sheet. It only showed the spark plug no mention of the decompression valve. He handed it to me and said he put it in as a warranty repair, so he made some money on it, I guess. When I started to replace it, and removed the rubber cap, I saw a dry shaft in new rubber, I sprayed some liquid graphite on the shaft, waited for it to dry and it functioned perfectly. The H and L adjustments were turned maxed out. There had never been any gas in the tank, it was dry as a bone, so I know he never tested or setup my saw before selling it to me, came right off the shelf. It had a Rotary Copperhead Full Chisel chain on it. Come to find out later, he orders the head, the bar and the chains separately. No boxes, I saw one come in UPS while I was there. He is also the Echo Service Center in my area. Don't know if he would go to bat for me if I had another issue under warranty, but I doubt it. Here's the chart Echo uses in diagnosing engine failure analysis.
