Bowtiedrooster16 Tell me about your kit for Schindler inverted 330a please. Done quite a few of these, and now we just turn them down (maybe we just aren't efficient enough). But we are pretty good at the TKs and pretty efficient. And yes, you are right, pit is always a mess on arrival. We had one with about 2 feet of oil in it. But if you keep adding to get by, that is what you get.
