Husky e 245

I took the nest with me, I'll inspect it for melt when I get home. It was like a soft and cheap accessory cord rather than a builder's string or polyprop, but sadly, definitely not rafia or hemp or something. 

 

Is it the sort of thing that can be fixed with removal of parts and cleaning, or full replacement of some pieces?

 

I don't make any claims to my ability beyond basic maintenance, I might have to watch a bit of youtube on how to remove clutch! I've not done it since 2017 on my CS30...

Re reading your earlier post it isn't clear that the clutch drum is spinning freely on its needle bearing

You'll need to take the clutch off and clean it all out, check the oil pump drive etc. and grease the clutch bearing. I had similar with my 135 years ago.

Hm, very annoying. Clutch and sprocket off, nothing visibily damaged or dirtied (to my inexperienced eye, at least!).

Idles fine with no bar, but cuts out straight away with bar and chain added.

That sprocket is fit for the bin, anything more than a light indentation and it needs replacing.

Will do, cheers.

I was going to try to describe it like a bike derailleur.

 

It needs to be able to move smoothly around the sprocket under load, a groove can cause it to strain the chain, like being in high gear going up a hill.

I guess from what you say something is causing a drag on the crank journal, so worn sprocket bearing, or worse wear on the crank journal allowing the drum to pull sideways when the chain is tension, this in turn allows the back of the clutch to drag on the inside of the drum, just as a short experiment space the clutch out with a suitable washer and try again.

Just change the sprocket, had the same issue on a mates top handle MS201T I got asked to repair the other week.

 

Similar worn out sprocket, fitted new sprocket, needle bearing and clutch springs as one had snapped. Almost like a new saw for about £50 including new AV bushings.

 

Plus that's a husqvarna style outbound clutch, you can't use a spacer as it drives the oil pump via the ends of the teeth.

Take the oil pump drive out. If it is stuck to the crank it will drive the clutch instead of the other way round
