I have not read every thread, but have you done a smoke test? I tracked down an annoying vacuum leak on mine that way. Spraying easy start around did not work at all.
Sorry for jumping in a bit late. You said in your first post that when you removed the oil cap the idle changed and per your video . Did you notice any pressure when you removed your oil cap? would the crankcase ventilation have some to do with this?
