Hi Mike
Not sure on hours but think that a four stroke will generaly last much longer than a 2 stroke, assuming same treatment etc.
However I firmly belive that engines that have VERY few engine hours on that are quite old may be in a worse condition than a engine of same age with quite a few hours on. They need a regular run to keep all surfaces covered in oil etc to help prevent corrosion etc.
Regards Gary
