Hayter Spirit 41 Push Mower

Great classic British mower in excellent condition. Is 3 years only my dad got it last serviced last year and paid £100.  Only problem with it is it starts but won t keep running but that might just be me as I have no idea how these things work. I m an electric mower man.  Hadn t been used all summer as my dad isn t very well and u will obviously need to pick it up but it looks brand new.
