Re: 100:1 Mix
A brand new China engine, just beginning it's life, should be left alone to 4-stroke a bit until the break in is completed. Things will change within the engine as it breaks in and you will need to tune it up after break in anyways, so why make twice the work for yourself and tune it twice?
