Warm up the engine. Disconnect the EACV wire (it plugs in on the right of it) and twist in the adjuster screw on the throttle body. Keep adjusting it until it idles nice at ~750rpm, then plug the EACV back in.
I got a new shell, just need to stop driving the DX so I can work on it.
I've got a filter for my mouth, it just isn't a good one.
