Thanks Matt for the info. They are quiting when returning to level flight from my up lines. the engines run good at full throttle but when throttling back on the down lines the engine dies. Would this mean I need to richen the low side?
Yes try going a little richer on the low end. As these engines break-in, they have a tendency to run slightly leaner. This could be the reason your engine quits. Suggest you use the pinch test at both the high and low end to determine correct mixture. Much has been written about this method and you should be able to read plenty - just search for "pinch test", or "pinch".
