Yesterday I got this little guy on one of the 20% off sales events Echo has when their dealers have an "open house" event. $300 out the door was too much temptation to resist. Quite literally half the cost of the next most desirable arborist saw in this size; the Stihl MS201T. Frankly, I don't need another $700 chainsaw, and this is a "luxury" item for me right now. I wouldn't have even gotten it had I not sold off a couple other pieces of OPE my sister and BIL gave me. Thanks sis!
True to form, I immediately ripped out the carb limiters and disabled them; because you cannot tune a saw without being able to make it bog down. Sorry EPA, you failed.
Then like every red blooded American, I proceeded to modify it to make more power. Echo uses these little two-piece stamped port covers on lots of their equipment, and it makes it really easy to open up the exhaust outlet without actually cutting anything on the saw. I modified the original on my other 34cc Echo, but this time I decided to start from scratch.
Once that was cut out, I transferred over the port dimensions and went over to my short materials rack and found a desirable piece of tubing and whipped up a deflector with a bit more breathing room.
Then the last bit of the fabrication was to slightly enlarge the opening in the muffler shield so the metal wouldn't touch the plastic.
It's currently drying, having been sprayed with a coat of high temp flat black BBQ paint.
What sucks is that we're supposed to get nothing but rain for the next 2-3 days, and I have trees that need pruning with this little guy.
Some guys advance the timing on these too, but I don't know if the gains are desirable for my uses. It adds some top end, but at the expense of torque. I think I'd rather have the torque.
