Chainsaw Repair

 Those muff modded CS400 Echo saws (I have 3 of them)make quite a few saws look crappy like my 53cc Rancher 55, my CS440  45cc and it was 1 seconds slower in a 16 seconds cut than my good running 029 Stihl 56cc which I sold. The only reason I had that 029 was that when I was tuning it up I let the owner use one of my CS400 saws, sure enough a week later he wanted to trade even up, I did as i only had $85 into that one.  Got $200 for the 029.   Steve
