       my NF seems to be running rich; The spark plug sooted up and
       stopped sparking until I cleaned it; Is there a mixture
       adjustment on the carb or could it be a worn needle?   Many
       thanks for any info,

       Could be any number of things.
       The only adjustment is the pilot jet which has little influence
       above tickover.
       When my plug has fouled with soot, it's usually been caused by
       failure of the coil (twice) and condenser (once).
       If you're sure it's carburettor, the first thing to check is the
       enrichener plunger. There's a rubber seal at the bottom which is
       supposed to stop fuel passing except when the enrichener is
       open. The rubber hardens and perishes, and can then allow fuel
       to pass even when the enrichener (choke) is closed.
       Obviously, make sure the cable for the enrichener is seated and
       adjusted correctly, so the plunger is fully down.
       That's the most likely cause.

       Had a similar issue with mine  when i first got it  years ago ,
       it was the choke  cable seating at the carb , the cable wasnt
       returning the plunger fully , i replaced the cable and adjusted
       it , no problem since
       cheers
