The plane I had in mind for this was a SPAD CLT (Cub Like Thing). And thanks for the encouraging words on the float carby. The walbro carb is impossible to find in this part of the world.

So the Q stands, If a maintain the fuel supply using a fuel pump for e.g. like the the one used for fuelling, rather than gravity, will that suffice? There is a way to feed fuel using a simple tank and pump arrangement like the one used to pump water to the windshield. But using this kind of arrangement, wont the float carb overflow if the pressure is greater than the one exterted in typical gravity feeds?

Is there any other type of easily available carby used in bikes, automobiles etc which is not too tempramental to odd aircraft attitudes? I was thinking, these stunt dirt bikes go all over the place and yet keep running... dont they use a float type carby?
