Why does the Rotax's Bing 64 use a starting carburetor instead of a real choke?

Safety. Suppose you are full power on takeoff. Your hand is on the throttle, as it should be. Your girlfriend's little brother, who is riding shotgun decides to pull (or push) on the choke (or enrichener) knob. What happens if it is a standard choke? What happens if it is an enrichener circuit?

Nothing nearly as bad as if he pulled a chute or went full flaps at high speed or feather at full throttle. ;)

I don't fly with kids who like pressing buttons and knobs without regard to safety.
