The carbs are brand new ?? But I will check height of floats and adjust to the heavy side and see if I can get to run rich. thanks for the help guys love flying this plane.

Just because they are new doesn't mean they don't have bad or badly adjusted floats in them. There have been several series of bad floats coming out of Rotax (Bing) in recent years.
I agree with Danzer1, those jets are unnecessarily huge and masking a different problem. What about the rubber boots between the manifolds and carbs? What about the o-rings on the intake manifold to head seam?
It has been suggested before, but have you checked your vent lines.
These make a huge difference.if they are vented into the K&N type filters like mine you will need to be up a jet size or two.
Mine are vented into the K&N filters and needed no jet change from the standard.

I need to check the float height but seems to me if floats were low you would run out of gas at WOT on take off I have replaced all the rubber O rings and carb flange boots and ran motor spray down intake manifolds looking for leaks it is good but I’m not giving up . Guys have a great 4th holiday
Maybe the exact location of the vent pipe in the air cleaner is the reason there can be variables.Me engine runs at 1550f egt,vented internally,but lower when clipped to the carb.
