Todd, that speckled stuff on the brass throttle butterfly isn't overspray. It's condensed hydrocarbons and 'tars' , byproducts of the combustion process. The butterfly is always 'cool' when the engine is running and guck condenses out of the airstream. It builds to a point where it begins to affect idle quality. At that point we do a "throttle body cleaning" using bottle brushes and throttle body cleaner to make everything nice and shiny again.
You don't have near enough guck (technical term) to worry about yet.
When you start the engine (WITH THE COOLING SYSTEM CAP ON) let it run until your temp indicator is in the normal range, maybe let the fan come on one time. Then shut the engine off and refill the radiator and coolant bottle AFTER the engine cools down. You'll then be all set, no air.
Always squeeze your hoses to ensure they are soft before opening the cooling system. You don't want "Old Faithful" in your garage!
