I have been working with a new Echo (CS-400) saw since Hurricane Irene mowed through the area, and have probably cut down or cleaned up over 25 trees in the last 3 weeks. The saw has been working great, and I am near the point where I will run it dry and put it into storage for the next emergency.
The Echo manual suggests doing carb adjustment after the saw has broken in (they say after two tanks of gas, and I am well past that point). But the saw runs excellent over the whole speed range once it's warmed up, and I am hesitant to fiddle with the carb at all. Does it make sense to just leave it alone? Without a tach, I doubt I can tune it any better by ear than it's already running.
I did rebuild the carb on a 40 year old Poulan (S25DA) recently and got that running in tip top shape, which was fun. The saw is practically a family heirloom, having cleared land and heated homes over two generations so far.
Thanks,
