Yup. With my Mountfield petrol mower, every spring I would need to
empty out any remaining fuel and replace with fresh, then also take the
spark plug out and bake it in the oven for a while. If I didn't do
this, there was no way in the world it would start, but with this
procedure, it always started on the first pull.
