Chainsaw (Downfield DD3)

Petrol chainsaw, unbranded, bottle of 2- stroke oil, chainsaw tools, instruction manual.
I’ve used this twice, It’s been in a shed for a good few years now, and may require
a bit of an overhaul, spark plug etc. I don’t know if this works with E10 petrol.
Chain and bar in good condition, body could do with a clean.
