Well, I guess the title says it all. But first let me say that my trusty Stihl 041 is still sitting in the wings ready and able to chew anything in it's path. However, ,it is getting heavier as the sands of time go trickling buy. So on another thread I stated that I would never buy another Stihl and I am sticking to that statement. The new replacement is a Echo CS-590.$379. Well the first order of business was removing the restricting baffle off the muffler. Then cutting the tabs off the limiter caps. This saw was running very lean from the get go. So hopefully I will get to run it later this week. A compression check was implemented. 175 PSI. Yes it does have a decompression valve and I will use it as the saw has already left it's mark on my hand. Hopefully this will be my last saw for a while. My new addition has already made itself comfortable settling next to another Echo, along with a Shinny ,and a couple of Stihls, and a Husky. Any words of advise on the new addition?
