Hello all,
I stumbled across this site after researching a problem I am having with my, new this season, Husq. 440 saw.
First off I want to state that this is the first saw I have owned, I have operated other saws on various occasions but never have owned one myself. This season I did some digging to find out what was a decent saw that offered enough power to handle clearing select trees from my property this spring/summer. I am fairly mechanical and feel fairly comfortable working on my own tools. With that said , let me outline the issue I am having...
So the saw ran perfectly for the first week or so, then after a long day of work on Friday I left my saw sitting over the weekend. When I came back to it Monday, the pull cord was extremely hard to pull. It felt very Jumpy and would catch, and then pull a small amount, catch again, and continue. I am able to get it started despite this, and when it does start it runs perfectly. I did some digging and found that someone mentioned that they were able to fix what appeared to be the same issue that I am having by removing the plug and giving the engine a few turns at that point, and replacing the plug. I removed the plug and the pull cord pulled as smoothly as ever with the plug OUT. after I replaced the plug, it went back to it's old, hard to pull ways. Tomorrow I am going to check the exhaust and see if its gummed up to the point where air cannot escape, which could be contributing to the compression issue I am having where I cannot seem to decompress the engine enough to turn it? Even when I use the little compression dimple/bubble it doesn't seem to have an effect on making it any easier to pull. Could this be an issue caused by not running premium fuel in my mix ( I didn't know until I read about maintaining my saw, oops! ) for 2 tanks? I also read that someone recommends using SeaFoam to try to clean out any fuel blockage problems in the engine. Sorry for this being so long, just trying to give an accurate description of my problem so I can try to fix it.
Thanks ahead of time, hope we can figure this out.
