Hi Ted,
You have been dealing with this rum rum noise for quite some time now and I think I've read that you have already performed carburetor synchronizing.
When I rode motorcycles, riding alongside of another cycle, I would hear this kind of rum rum noise. Two engines out of sync. Do twin engine aircraft make this noise if the throttles are out of sync?
The Rotax 912 is kind of like two separate engines in a way (with two carbs feeding separate cylinders, separate exhausts, etc.) and just maybe this could be a factor.
Anyway, I do hope you find the answer sometime. Keep on keeping on.
