I just picked up a 123R missing the pot, but packed in the original box with a mini-pump and cap included. Aside from the pot, two issues are waiting to be fettled back at home: the main valve won't turn left or right. The cleaning needle is in place, the packing nut comes off, but the valve shaft won't turn. Does it just require extra oomph, penetrating oil, heat, or ? Second, when attached to the cap, the mini pump builds pressure, but the NRV in the cap doesn't allow pressure through. Is it just the pip is stuck and a gentle poke will free it up? There is an old spare parts kit with it, but i don't think there's a pip in it. Any suggestions welcome.
