I would recommend to everyone that they take extra care in inspecting the the air intakes tubes on their Carbon cubs the next time they have the chance.
I had one work loose and while it very luckily happened on the ground, it would have been a disaster just a few minutes earlier. The flexible plastic tubing that connects the metal intake for the the right rear cylinder worked loose as you can see in the attached picture. This resulted in a huge vacuum leak. This caused the engine to quit when power was reduced below 2000 rpm. I would recommend everyone inspect this area. My other intakes seem fine. In looking at it it doesn't seems like it would be able to come loose but obviously it can.
Has anyone else had this issue? I have a little over 400 hours on my engine.
