Just bought the 160 used from a guy, and went to take it apart and clean it up. I am trying get the bottom bubble plate screwed back into the pump. No matter how or where I start to screw it on, it tightens down opposite of the position it needs to be in, and if I keep twisting it slips off the threads. Is it possible that I have stripped the threads??!! Because I cannot seem to get it to tighten up, and the result is a loose bubble plate and a gap allowing big bubbles which will not work.
Anybody have experience with this?
