For a two stroke engine to work properly it has to be an efficient pump, and to achieve this the internal parts have to be sealed from the atmosphere this is achieved by coating them in oil, if your engine was assembled more than 3 or 4 months ago the chances are that the oil used in assembly has evaporated, we are talking mainly about piston sealing and glands, both can be rectified by liberal use of an oil can and won`t require removing the engine probably just oil pipes from crankcase unions, transfer covers and mabe the carburettor, when everything is OK you should hear a distinctive plop plop plop as you kick it over, good luck.
