I've ordered (and not yet received) an 80cc typical 2-stroke Chinese engine kit, and I am kind of hoping I'll be able to fit it to my 18" GT Tempest Triple Triangle Frame. Seems like it's doubtful, but I'm still hoping!

Any pointers or opinions are welcome. Seems like I would have to change the location of the carb?

I voted carb needs relocation for those are nearly the same dimensions as in my Diamondback without that extra area then I barely had enough room with my front tube a bit too thick yours being even thicker.
I say if worst comes to worst,it's a stiff frame. You can get a 20 dollar garage sale/flea market mountain bike they are EVERYWHERE and swap out the frames. Bring your ruler.
You also get a whole lotta parts this way too.
At a guess i'de say it's gonna be a REALLY tight fit but the only way to tell for sure is wait for your engine to arrive and do a full "mock-up" with the carby/sparkplug/carby intake manifold installed.These engines are VERY tolerant about what angle their mounted at(within reason ofcourse) so don't be afraid to slope the engine foreward.
The carby's intake manifold can also be shortened or even replaced(but it's not recommended)
Let's just see how yours goes before we start talking about grinding the engine down or other radical modifications.
