Where in the country are you? One of us maybe local enough to just pop round and take a look.

I'm in Derbyshire Eric Heanor. to be precise.

Ok. So, what was the reasoning with putting oil in there in the first place?  

 

I was advised by someone ,a car mechanic actually he reasoning was that in order to get it started  because it had not run for 3 years wa to let the oil give it an helping hand when all it has done is hinder.

Ok, thanks for clarification. ... seems i misunderstood, got the wrong end of the stick, etc, etc.

As others pointed out, if it turns easily with the plug out, there is no need to be looking at clutches,  chain brake, ignition coil foulIng the flywheel - my mistake,  apologies. 

 

Still worth posting a picture of the piston  seen through the exhaust,  or at least confirm the piston is good. You should see the faint machining lines running around the bottom half of the piston, so below the piston ring. Any vertical lines are damage. There's a thread here just recently "Does this cylinder need replacing" with some good pictures in it.

 

So have you managed to get any gunk (oil) out of the saw ?

 

Keep us posted.

I'm close to Jn 16 on the M1,  bit of a trek but happy to help ...

Oh so quite close then,i'm treading water with it at the moment so this might be an option.

About 13 miles if you want to get a second opinion on it. I'm in Clay Cross. If you want a professional opinion there's Belmont Stihl dealer in South Normanton.

Ok here are some pictures of the cylinder and piston.I have done what Spud suggested so i'm just going to put the muffler back on to see if it's pulling over as it should do fingers crossed.

Piston's Peachy.

No problems there.

 

Strange exhaust port though, bit difficult to make out the shape,  not seen one like that before. ....

Is it a genuine cylinder I wonder ?

Did you get much oil out of it? 

 

Put the clutch drum back on (if you haven't already) before firing it up.

yeah its a oem cylinder and piston, I always think when seeing a ms171 ms181 ms211 piston that the speeds and feeds on the lathe have been wrong and left a poor surface finish, but it looks like all the original parts ive seen. Nice that offers of help are there, shouldn't be too long before this saw is up and running again.
