Rotax's carburator
What's the difference beetween Rotax's carburator and the regular Lycoming's one?
That's just the altitude compensating feature?
I think mixture management is crucial in any operation. It's not so hard to lear how to manage the red knob. That's why most pilots are afraid of touching it: they have never been taught to!
Simply compensating altitude is not enough - by leaning the mixture during climb, I can get back a lot of the lost power. What about high elevation fields?!
Anyway, in ultralights we have no choice but the Rotax. I hope the overall engine performs well and shows good reliability. That's enough for a 80-100HP engine.
My main concern is about AVGAS. I just read that the manufacturer recomends to cut in half all service intervals for engines running on AVGAS. I think most of that problem could be avoided with a simple mixture control. The main reason for a stupidity like this may be the 2 carburator configuration in the Rotax (to make it more compact). It would require two mixture levers, probably.
