What I find weird is that Chapter 4 mentions Chapter 5 which by definition is not under Airworthiness Limitations since it is another chapter.
5 is not 4 (obvious), and this statement from Rotax is just a dirty trick. That’s all. Some people will fall for it and they will get money for that.

I have heard of several having trouble with “synchronization” of carbs.
Synchronising carburettors is an absolute doddle… if you can stand next to the running engine and fiddle with it.
Propellors can be problematic!

Synchronising carburettors
What does it even mean?
It means to adjust both of them so the operate in synch. The same throttle setting, the same idle setting. One carb supplies the left side of the engine, the other carb the right side.
Or in other words (using ‘pilot speak’) carb synchronization is adjusting the throttles so that the left intake manifold and right manifold have the same MP at all cockpit throttle control positions.

That was very well said :-)
So the Rotax engines have dual carburettors?
Unfortunately yes :)
Get the fuel injected versions (912/915 iS) instead ;-)
We synced my 912 ULS carbs when we installed the engine in my RV12 2 years ago. On each subsequent check they’ve been absolutely fine with no adjustment needed. It really isn’t a big deal.
