I have this vision of this difficult to start engine - where I have the hassle of mixing oil and petrol. Where there is such a long gap in time between each time I might used it, the petrol will also have lost all it's volatile constituents making it even more difficult to start.
Perhaps someone will come along and say with modern electronic ignition and injection, self oil mixing that my experiences are long left in the past?
Personally I'd get an electric one, and if I didn't have a long enough cord I'd use a generator which can be used for other appliances as well!
