Well I started the mower up tonight and still the same issues. It goes ok when its cold but as soon as you stop it and start it up again it coughs and splutters really badly and seems like its going to stall. The mower does start really easy.
A further issue that arose was sparks coming from the engine on the side of the carby. I checked the spark plug lead and it doesnt have any cracks.
All o rings have been done along with the bottom seal. Carby has been fully serviced with all new seals.
Id appreciate some help as Im out of ideas. I dont want to put it aside as its in really good condition.
