well I got the engine cleaned up today and went through the carb .... no blockages or gunk or anything. I was trying to figure out how to test the Ignition for spark, any ideas?. As abruptly as she quit it seems like it lost spark , gonna take a look at my smart-fly optical kill also although the Indicator light was still working when I checked it at the field so I was just assuming that it still worked properly. I kinda think the ignition is the problem .
