Have a look at THIS if you haven't already, page 2 in particular. My problem turned out to be something else, but it's still good for WUR info. In outline the process is: First is getting hot pressure right with the big cylindical valve body. The thermoactivator needs to be removed. Second is setting cold pressure using the indented plug on the top of the WUR with thermoactivator reinstalled. Last, vac enrichment, the bottom one is vacuum enrichment and acts only on the diaphragm in the lower chamber. I think there's a thread on that. It's easy to overdo it. S Class says that doing so will wreck to diaphragm. Good luck! Cheers,
