   Hopefully someone will come along with more experience than I.  But I   
   will try to get this conversation started   
      
   You haven't mentioned trying the mixture adjustment, which should be   
   separate from the adjustment on the zero regulator.   
      
   Very basic, is fuel pressure.  You should find the specification with   
   the conversion kit.  It is measured in inches of water.   You can buy a   
   gauge, or make your own manometer from some clear tubing and a yardstick   
   like I did.  You may find that your fuel pressure under load goes too   
   low.  That could be anything from a simple fuel regulator adjustment, to   
   the need for a larger (or more direct) fuel supply line.  There should   
   be measurement ports for both the inlet and outlet of your zero regulator.   
      
   I have had the same zero regulator since my ancient Onan was factory   
   new, and don't remember ever adjusting it.  My mixture adjustment   
   however, is another matter.
