Hey all.

I’m having a problem with my 55ra. When I advance the throttle it sounds like it’s occillating thru several hundred rpm. A guy at my field though that the ignition isn’t advancing was causing the problem. Would it hurt to try a #6 ignition from a dle20ra to see if the problem goes away? It currently has a #5. Not sure what the difference is but figure it’s probably the curve of the advance or something similar.
