Should the check weight in the upper part of the bowl casting come free just with gravity or is something else there to retain it?
Seems rather immobile despite all the soaking in various chemicals. Thought about applying some strategic heat but will not do that without someone much smarter than me advising it.
Likewise with the check ball in the pump casting piece. It is still partially encrusted. I see a ring there to retain it. But not sure if that is designed to be removed.
Aside from those two issues, things are cleaning up pretty nicely.
