Yep, checked my primary when I had the TB out. It was pretty dirty, so cleaned it up a bit with brake cleaner.. Didn't have quite as much daylight around it as I see in your picture.. Secondary blades had virtually NO light showing around them.. I feel like I'm chasing a rabbit here for which there is no real symptom.. The engine idles well, never stalls when I come to a stop and pulls like crazy all the way to 7500 (no courage to go higher than this!).
