I'm betting on a genuine honda, tank matches, muffler matches, what I can see of the air box matches, right color red, everything looks honda. Carb on my gx160 says Kei hin, so with that all said, add in the electric start and yes it would be worth reviving if it can be revived. Only difference I see between yours and mine is I've installed a red honda tank, but I can post a picture or two if youd like.
