I posted a while back when I started to have problems with my evo trainer engine, it just started to die while attempting touch and go's. It seems that the bottom end was a little lean, making it richer solved that problem. Now it seems like it won't rev out well in the air. It reaches a nice smooth high rpm on the ground but when I go to take off and fly it doesn't rev out well. If I put it into a dive with full throttle it revs out nice and stays until I back off. When I level it out and reduce throttle then try to go back to full throttle it won't rev out again. The high end needle seems to be set right. I did the pinch test and the rpms increased slightly before dying. Any suggestions would be greatly appreciated. I don't really want to dump my plane because of engine problems.

Thanks

P.S. It is mounted on a H9 Arrow.
