       newbie of a certain age

       Hello, I am Warna, (male, to prevent misunderstandings) and I
       own a Falcone militare of 1971. Quite old, but not as old as I
       am (74).
       I own the bike for some 20 years and as it resides in a French
       farm some 350 kms from my home in Amsterdam, it is not ridden
       regularly. I also own a Matchless (G3LS from 1954) and a Honda
       dirtbike (XLR250 form the nineties).
       The Guzzi always served me very well, but there is a thing that
       bothers me: the spark plug is always black and sooty, and I have
       to clean the plug quite often. So the mixture is too rich, I
       suppose. I cleaned the carburetor several times, and sticked to
       the standard settings. Maybe lower the needle might be a
       solution? It is now in the middle position. Or a different spark
       plug? It now is a NGK BP7ES.
       Anyway, great to discover this forum dedicated to the Italian
       beast, and I hope to return here evrey now and then.

       Hi Warna, and sorry for the VERY long delay in welcoming you to
       our forum.
       Sadly, there's not much traffic on here these days, and so I do
       not check for posts as often as I should....
       The plug won't be black because of the heat grade of the plug.
       B6 or B7 are normal choices, but sooting can be caused by many
       things.
       In my experience over the past 20 years, the most likely causes
       are the rubber sealing face of the enrichener plunger, but the
       worst cases have actually been caused by ignition problems.
       The last two times I have had serious sooting problems have been
       caused by the coil breaking down (I replaced it with a Lucas
       from BL Mini) and failure of the condenser.
       Hope that's some help in diagnosing your problems, and apologies
       again for the delay!
