Doesn't look in bad shape. I would check the sprocket out for wear. Many of the machines I get in end up with new sprocket drums as nobody seems to replace them! I check the end of the sprocket lobes to make sure they don't have indentations in them. If they do, the sprocket is on it's way.

Clutch springs can be worn, if the clutch side makes a ring pinging noise then either the idle is too high or the clutch springs are worn. 

Make sure the chain catcher is OK and make sure the chain brake works OK.

Make sure you keep the air filter clean and see how it goes. Not bad little machines.

 

Hmmm so thinking new drive sprocket needed then 🙈  also the E clip came off ok but now seems loose looks like chain has come off before at marks on the case where is the catcher? In the cover?

Seen a lot worse !

The drum is past its best and I would replace it as it isn't going to get any better and is best done whilst you are in the middle of  being focused on servicing it. As Andy says, not as bad as some we see but in the repair game, if I leave something like this, next time it comes back in a year, it will be hanging and it is what I get paid to do.

The chain catcher on these saws is built in to the side cover and hooks round below the chain locating in to the hole on the area under the bar mount. It is just an extension part of the side cover molding.

If it has been taken off with a chain coming off, you can either use a bolt put through the hole so a chain coming off will wrap on to it or more favorably, fit a new cover.

Looks like the chain has come off before and taken the catcher with it drum is £17 cover is? E clip is 25p but bearing for drum is £5 worth doing bearing if doing cover? 
 

does it need to be special grease for the bearing? 
 

BTW thanks for the answers I get that is your day job and pays your bills

Looks like the stub is just under the bar mount. The new cover is here, I use L&S for most of my spares, very good outfit and their prices are pretty good. As far as grease, just use LM grease, it will fly out first time you start the machine and isn't really something to get hung up on: -

Thanks @spudulike yeah I know of L&S and have used them for parts for my kombi units. 
 

When I was  taking the picture I noticed the E clip had made a break for it 🤷‍♂️
 

weirdly they are mega expensive for the 2in1 file 🤷‍♂️ Shame I can’t just pop to TFM and pick up what I need 😞

Sometimes they get online prices wrong, you could phone and ask. 

I was getting a full Mtronic MS201 handle for £14 for a year or two.....all linkages and wiring assembled. It then went up to £60!!!

Seemed odd radmore and tucker £28 L&S £47!

You dont need a new side cover just for the chain catcher, there is a chain catcher available that fits in to the bottom av buffer.
