DLE 55 Engine Issue - Help please
I have a DLE 55. It ran fine for some 4 flights but what happens now is that when I push the throttle to anywhere more than 50% the engine goes into a smooth consistent 2 seconds cycle of going to max RPM and the dropping to mid RPM(i dont know what this phenomena is called). I have fiddled all I could with the low and high needles but no use. Can it be the ignition system or something else? Thankx in advance
