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!
