    When on both natural gas and propane, on 2 generators, and 2 propane   
   regulators, and 4 propane tanks (2 at a time on each generator) I have   
   the same problem.(actually, the second generator has never been run on   
   natural gas) The natural gas pressure has been verified.7.5"wc at the   
   quick connect  with furnace and water heater both running . Have not   
   verified the propane pressure, but the regulators were both supplied   
   by US CArburetor for the application. Pressure has not been verified   
   at the zero regulator.   
      
    And regardless, NO-ONE has answered my question on how to adjust the   
   spring pressure on the Century Zero Regulator - or even what the   
   effect of pilot vacuum being higher or lower than spec would be.   
      
   I've googled it all kinds of ways and have found nothing.
