Installing a new bar and chain on our Echo CS-310 to see if we can midigate the chain jumping issue we have had with this particular saw. This issue has ruined 4 chains to date. Is this an echo issue? Edited by YouCut:youcutapp.page...
I have had a Echo CS-310 for over 11 years, purchased in 2012. The primer bulb and fuel lines are still pliable and in good condition. I will use pump gas mixed with 2-stroke oil for any large amount of cutting since it saves money. But before putting the saw away at the end of the day I drain out all of the pump gas, run the engine 'till it dies, and then refill the tank with the expensive gas/oil mix from Home Depot or Lowes. Run the engine a minute to purge the ethanol out of the carburetor/primer bulb/plastic fuel lines. Then drain the tank again (saving it in the pump gas jug). Run the engine some more until it completely runs out of gas, pump the primer bulb and pulling on the starter rope until it does not even sputter any more. Then I will put it away. Hard lesson learned that something will always come up the next day which leads to weeks and months before the chainsaw is fired up again to do all of the intended chainsawing. By then the gas has started gumming up and the ethanol has destroyed the plastic fuel lines and primer bulb. Does anyone purge the fuel system with transmission fluid for long term lay-up? I have heard this keeps the fuel system in excellent shape over a long winter.
I also have the Echo CS-310. The bar stud stripped out the plastic hole it screws into, now the stud just spins in the hole when I try to tighten the nut. Is there an oversized replacement stud that can screw into the stripped out hole?
I think you will need to install a thread repair insert into the hole. There are special ones designed to be used with plastic. There is a company in the US that makes these. I Don't recall the name of the company but with a little digging you can find them
Wow you got me LOL There is no upside down on a bar. you aew supposed to flip them regularly to even out the wear on the bar and get more life out of them
Thank you for pointing out how that screw lines up the pin that goes into the bar. I struggled and struggled with this and couldn't figure out why I couldn't get the cover back on. Your explanation helped immensely!
