Re: 1st build in the mail!!
So long as the carburetor is reasonably level and the chain can still get to the rear wheel you can mount a 2-stroke engine in any position you please. There is no up or down on them. They don't care. They will happily run upside down if you want them to. As far as proper sprocket rotation out of the transmission, there is a left and right side. You cannot mount the engine backwards and expect the bicycle to go forwards.
You may have to fabricate an intake manifold if you get really creative with the mounting angle though.
