My 490 does that now and then. I leave the bar/chain on the saw and push the chain backwards on a log to free the nose sprocket then pull the bar and clean all the crap out. Only seems to happen in Ash but maybe that's just me.Had the b&c lock up on the 550 again today. Thats twice. Both times cutting a log directly on the ground so I couldn't cut all the way through. Both times I let off the gas and let the chain stop in the cut (not loaded) before I pulled the bar out of the cut. I think that maybe an operator issue, but this is the only saw/bar/chain I have ever had the issue with. I don't think it has anything to do with the saw. Just OE or a b&c issue. I cleaned everything I could out of the bar but I still can't get the nose sprocket to loosen up. It's like there's stuff mashed in between the outside of the sprocket and the inside of the bar. I have a brand new backup bar that I put on but its the same exact bar. Any suggestions on a better bar? It's a 16" 325/050 66DL b&c. And while we are at it, I have heard good things about the "good" Stihl chain. Which one is that?
