'craft', short form of aircaft Jan, most after market motorcycle carbs come with this warning to avoid any confusion if using them on micro light aircraft, must be something to do with the altitude? I'm guessing that the aircraft carbs have some sort of heater circuit to prevent the fuel freezing?
Talking of the no-aircraft-use-badge, that has got (mostly) to do with liability issues and that every part of an airplane needs special approval to be used, which is why old Lycoming motors (as found in most smaller Cessnas) still run terribly inefficient Schebler carbs, which go back to the 40ies or 50ies, simply because type approval with the FAA is hillariously expensive.
There's a company here in Austria that wanted to install Volkswagen Turbodiesel engines in small aircraft, because they're immensely more fuel efficient (and less noisy) and they nearly went bust until they had fought it through...
My father and I built a air-cooled VW powered airplane that had a carb that was labeled "For Aircraft use only". I believe it was a Mikuni carburetor...that was set up under the motor in an 'up-draft' condition...as I recall my father saying, to prevent fire if something was to go amiss with the carb....preventing fuel spilling on the hot motor...which was interesting as the four question mark shaped fire spewing un-muffled exhaust pipes terminated very close to the bottom of the motor...
My precious!, live the shot of Loveless through the carb. What's "craft" use?

Gorgeous piece of kit you got yourself there!
