I ran the Eco 4910 to cut up a couple of small trees and the limbs attached to it. I like it – easy to use and I could feel that it was a little lighter than my husky 450. Got the call from the repair shop today and the Husky will be more to fix them to buy new. Bummer. I asked the guy what happened from what he could see and he said that it was probably an issue of running hot – either from running the saw very low the ground with wood chips gathering near the air exhaust. I thought this was very unlikely knowing how I typically use the saw. The other thing he mentioned was “running the saw lean”. I was a little bit unclear on exactly how I did this, but I do know that in about eight or nine years of having that saw, I never once did any sort of maintenance on it. Only just had the right gas Oilratio and bar and chain oil. Perhaps if I serviced it even every couple years I might’ve avoided this. With this new saw, I’m gonna work towards doing some of the basic maintenance stuff myself.
The shop should give you more specific info on damage. The 4910 is a great choice, congrats. Sent from my SM-G960U using Tapatalk
I have to agree on this one. I would not accept that diagnosis. If they cannot even give you a good explanation of what failed how can they say it is not cost effective to repair.
I would suspect scored piston/cylinder. With that alone, oem cost for replacement plus labor is definitely killer for a well used homeowner saw like yours. Never know till you dig in. Bottom end rarely lets go though, at least that I've heard of.
Some real good advice in here. I know I learned a few things. Kind of reminds me of advice floating around about motorcycles I'm familiar enough with to get the gist but not well enough to quote it correctly- but it goes something like: there isn't a motorcycle made that you can't ride better. Learn the machine and become a better user is the basic thought.
Did you see this video? running hot could have been just an issue of not blowing it out. shoot, bring it home and take it down yourself and see what you can learn. may need to buy a $17 ring compressor set. I found it on amazonion hoarder availability resource depletion website. Vid I found on YT - Chainsaw Maintenance
I think you will really like that saw. I have about 6 tanks through one. Compared to my stihl 029 and 290….well there is no comparison. Waaayyy more power and fewer cc,s and about 4 pounds lighter. Pulls a 20” bar with authority in dead dry elm….although I did mod the muffler and pulled the carb limiters before I ever fired it. Very impressive so far.
A little maintenance can go a long way. Do you have an air compressor? Blowing things out after cutting is a good start. This alone could prevent overheating by preventing things from getting clogged up with chips. Get your old saw back and start playing with it. Pull the cylinder off and check for it being all banged up and scored. You can get a cheap aftermarket cylinder and piston cheap. ( yeah I know it is not made anywhere around here) I did this for a Husky 455 that was given to me and I didn't want to dump a lot of money into it. Runs great and now is a great beater saw.
Thanks for the help everyone. I appreciate all the input. Weeping of oil was mentioned above. I noticed the new Echo drips more oil than my previous saw. How much is too much “weepage”?
