Petrol Garden Strimmer (Neville's Cross DH1)

McCulloch garden strimmer. Runs on petrol with added oil. Perfomed well for over a decade but more recently a bit truculent to start so needs someone to take a look at it. Did half the garden with it last night however. Petrol cap leaks a bit if stored the wrong way up but dealable. Collector will have to take it as seen with petrol in the tank, I am not draining it for you. Have instructions I think. Would be ideal for an allotment (which is what we had it for).
