Greetings stuart1866, May I extend a warm welcome to the ODK Forums.
As far as year of manufacture goes, we can get a pretty close estimate from the numbers on the engine. Presuming that it's original to the machine, that is.
The numbers are the Model, Type and Code; and they are to be found on the engine cowling, just above the spark plug.
Cheers, Gadge
