These questions may sound dumb but did you check the oil level of the
dashpots? Are the jets centered? The plug fouling is most likely caused
by the rings not seated yet. Do you think it is running rich or lean?
Sounds lean to me if you give it throttle and it dies. During idle, have
you tried to advance/retard the ignition? Are the carbs synch'd? What
happens to the idle when you lift a carb piston? Does the engine
increase in RPM for a few seconds? Are the throttle butterflys centered
and tight?
