Could be either, Yamaha made both a 2 and 4 stroke PW50, affectionately known as PeeWee. One way to tell is look for a dip=stick for crankcase oil. No dipstick= 2 stroke. Dipstick means a crankcase with oil. Check your owners manual, if it says to mix oil in gas,= 2 stroke.
If you mean who made the first combustion engine, i have no idea, but the first Four-Stroke engine was made by Nikolaus Otto.

There have been many examples of a 350cc two stroke engine made over the years. Kawasaki and Yamaha motorcycles used this type of engine as well as many other manufacturers.

a gasoline engine and a electric moter.
AS41 is the metal the crankcase is made from. It was used in engines up to 1975--when they changed to fuel injection.
