I owned a 200 back in the late 70´s. It needs oil mixed in with the gasoline. Typically you buy the two-stroke oil in its own bottle and measure it out on a per-gallon basis. I don´t remember what the ratio is of oil to gas or what kind of oil. You should be able to find the oil at either gas stations(US) or an auto parts store. It doesn´t go into a separate container. The oil burns up with the gas and lubes the cylinders at the same time.
