You'll have to strip it to properly access it. Crank cases are plastic I would have thought on them models so check for damage if its got so hot...

That's better.

 

Sw the last title and didn't bother posting as I knew it wouldn't be long before it was gone.

 

A side cover, you need to check the brake band is good and the clutch drum. The clutch itself MAY be ok but check all the springs and small plates are ok.

 

Any pictures?

My expensive mistake!

Oh.

 

Remove the clutch drum and all the plastics sourounding it, then have a good clean up.

 

The drum comes off with the clip. Then the two hex screws in the plastic. All this comes off and gives you s good look around the clutch area. The main parts are the braked band and clutch. Depending on how you want the saw depends on replacing the plastic parts.

my guess is that a new engine case may be required, seen lots like this.

Looks like you will need new plastic bits, new clutch, needle bearings, oil pump and maybe more

ouch!

[chopperpete]

The engine was still running before I turned it off, so hopefully the engine parts, oil pump will be ok. Is the plastic panel in the photo seperate to the main carcass, so easy to replace??

Yes very easy, but by the looks your needle cage has broken up, take the clutch drum off, and have a look behind it
