Not Ranked
Thanks everybody. I know the picture is not the best and I'll try to get a better angle and clarity. What I am concerned about are what appear to be tiny flecks of aluminum on the insulator. In the old days that was a sign of a lean engine, but this one runs really well without the other usual lean symptoms. Could it be too much antisieze as JB suggests? My primary jet is a 68, which feels like it would be too small for this engine. I was thinking a 72 is more inline, but performance tells the story.
