Thermoquad primary shaft leak

Oh, ok. Must be a sizeable leak/clearance for that much noise. Get it bushed first & proceed from there.
Im not sure if thats where the vacuum is leaking from thats what I'm asking. I do know when I wobble the shaft the idle changes. The vacuum leak noise could be changing because of that. Im not sure if should fix the carb or look elsewhere for the vacuum leak. Like I said I can't pinpoint it
