088 sound "odd"?

[mikecotterill]

Hi guys I put a post up about this a while ago at the time I thought the saw sounded odd, the advice given was to put a new decomp valve in which I did. I used it again at the weekend and there's a new noise now. It only does it when you lever the saw into the wood while cutting and sounds like there's a nail in the wood constantly. Any ideas? I've not checked yet but wondered if it could be the nose sprocket? Cheers people

Had this on my 088, after a bit of investigation I found the coil had moved just enough to make straight contact with flywheel. Just needed to be repositioned. Probably not your problem but that's hat I found.

Could be nose sprocket, or could be a dry, or worn, needle brg in the clutch drum.

Just had a quick look the bearing was dry so greased that, the nose sprocket has got a little play in it, perhaps half a mm, can you buy new ends? It's the type where it's replaceable? Cheers mike

Could as said also be the sprocket (needle) bearing - the one the drive sprocket runs on.

 

 

I had almost exactly the same thing a few weeks ago - looked at the needle bearing and it looked fine - changed it and the noise went.... worth investigating.
