altitude compensation
Would the same be true for the Rotax 914?

Uh, no. Not really.
They do a reasonable job up to about 4000ft, but above that the slide
lifts the needle out of the jet well and things get really rich. The
diaphragm can only do so much.
Not to be too hard on the Bings-they, like all carburetors are hoist
from the the same petard. Namely that carbs meter fuel to the VOLUME of
air and at 7000ft you have left 25% of the atmosphere, ie: oxygen,
behind and the carb is still adding fuel based on sea level proportions.
The solution is, of course, fuel injection.
