I was running the 026 clearing out overgrown bushes around the house and the saw locked up. Wasn't a good start to the day. I was convinced the piston locked up. Ended up setting it aside and coming back to it later in the day. After taking it apart I found the culprit, a screw came out of the back of the clutch and Had wedged in the clutch stopping it from moving. Ended up being a pretty easy fix. You can see the spring begins the spring in the pic
Not to make fun of your situation,but people have said that about me for years Related note,similar thing happened to me last year when one of the original clutch shoes on the 125C had an unknown crack,1 of its 2 screws wouldn't hold & it came loose & wedged behind the sprocket. For very little more than buying 3 new shoes alone I got a New Old Stock complete assembled clutch,with shoes,that circular spring,3 little plates & 6 screws.
I had almost the same thing happen on my PP5020 AV. Made a cut and right when I left off the throttle..."CLUNK!" things came to a dead stop. I thought maybe I had bumped the chain brake lever...nope. I pulled the rope and it did turn over but it was very difficult and there was a spot in each stroke that got even tougher...I was sure it was internal. I pulled the muffler...piston looked fine...hmmm. I made the last second decision to leave the flywheel on (just cause I could, and it would save me a lil time/trouble. Once I got the case split...nothing, things looked perfect, brand new even. It turns out that a carb screw had worked its way behind the flywheel! The kicker was that I was missing no screws...it must have been a stray that was there from when the saw was built and it finally worked its way down behind the flywheel. On a positive note, there was no real damage done and I was able to throw it right back together with no parts needed except some sealer for the case halves and the chips were flying again inside of 1.5 hrs.
Glad it didn't cost you more issues Sean. I've lost two screws and a rubber piece off the outside of my Echo CS 680. There is no Echo dealer nearby so I guess I'm going to have to look up the part numbers and order them.
Look up numbers and put them in ebay. I bet it's cheaper to get them at your house than if you had a dealer near by
No it was one of two screws behind the clutch. At first I thought I lost a screw while taking everything apart. But once I spun the clutch I could see where the missing screw went. Just above and left of where the screw was resting in this pic.
I thought it was internal too, but after pulling the muffler the cylinder looked great. I'm just glad I checked a little further bc I almost said "screw it" and took it to the dealer.
