My new 20 runs fine and strong above 3000 rpm. Below that the idle is ruff and I've had at least 8 dead-stick landings out of last 12 flights. Cut the throttle to idle and you just never know if it will keep running or not. New plug and hours of needle experiments haven't fixed the problem. Can this possibly be an EI problem????
