So I bought this old Ambo from a friend of mine, and have been
monkeying with it for a while, trying to fix the reason that he sold it
in the first place.
The left hand cylinder fires, but runs extreamly rich (black
exhaust and fauled plug). The other cylinder runs only at higher RPM.
I also discovered gas in the crankcase. After discusing this with wiser
men than I, we figured that it must be a carb problem. The floats are
probably bad, and both are running too much gas into the engine, one
side so much that it simply floods, and then runs into the crankcase.
Ok, seems like a good theory. New floats and needles. BUT, how to
adjust them? Is there any procedure to adjusting the floats? Neither
of my workshop manuals has one. Are there any mystical tricks to these
funky old Italian carbs?
Any help would be appriciated, as this problem has really been
agrivating me for a while now....
