Thanks Grumpy. Hopefully that manual will hold some part numbers etc. I read on another website that the saw owners manual has a list of illustrated part numbers but the thread dates back to 2008.

That video is great. I wish I had access to such a workshop. That finished saw looked a treat. I don't know if banging down with a bare hand on barrel studs whilst slipping over piston rings is a good business promotion ;)He did a great job though.
