Senecio:
When my wife and I moved into our first home together I picked up an old 2 stroke lawn mover from the side of the road that someone had left for council collection. A new spark plug, a new air filter and a spit and polish it started first pull with fresh fuel mix in it. It lasted for 10yrs without a further penny spent on it and survived not one but two floods. It might not have as fancy as the neighbour's fancy 4-stroke Honda but it did the job and cost me nothing.
A Masport 2-stroke with aluminium body? Those things last for *ever*.
