Good that you it idleing...makes checking everything else a whole lot easier. As to your comment on the valves not needing adjustment since there was no chatter, you actually want to hear a slight amount of chatter. Oilhead valves tighten up as they go out of adjustment and the chatter goes away. When you have time, adjust your valves while the motor is cool, then do your throttle bodies.
