I have an Evolution 58GX2 and I also have the midrange burble. Been playing with the needles and its gradually getting better. Here's the real question, when the plane is inverted why does the motor go rich? There is a nipple on the carb to run a vent line inside the fuse. Will this help even if there is a 3" hole in the firewall? The hole is there because the carb is sitting inside the motor box. I was under the understanding that the vent line is to help the motor get undisturbed air. Wouldn't the air still be disturbed because of the hole in the firewall?
Thanks

My 116 was the same way until I followed this method to a T. Now it is awsome. Your 58 is half of my 116 so they should tune a lot alike. When you first start your engine it should have that hesitation and not want to transition until it is completely warmed up. If it transitions well right away she will burble in the midrange when she is warmed up.
