I have put a few hundred hours on this motor all the while the same noise has been there. It is a very distinct knocking/Rattling noise that will only fade out if left in idle for 10 to 15 min:facepalm:. then it will slowly start to go away. When brought back up to WOT and back into idle it is there again. It can be cold or warm no change. Its noise is driving me crazy! I took a short video with my phone yesterday. Like I said I have put on a few hundred hours like this and I figure she would have blew by now if it were anything too serious..Im open to any thoughts. Please give me a direction Thanks 1990tuffy
