My sense/belief is that the car must be running rich if the plugs are blackened. True?
Can other conditions produce a carboned up plug?
If not, mixture must be leaned — although that leaves the unexplained addition of the helpful choking. The choke is pulled out very little in order to get that normal running feel.
i believe I need to take the beam out for a longer ride— operating temperature for more than an hour and check the plugs. This should reveal something I would think. Not such a bad way to spend an hour!!!
