nobody said that the ground could be eliminated....or to isolate the plugs from the cylinders.

the ground would still be there, just connected to a plug terminal instead of the case. the spark just has to jump two gaps instead of one in order to get to ground. plenty of opposed twins have used this system. the only problem in our case is how to keep the spark from choosing the hall sensor as a ground instead of the second plug. i have sensors and magnets that'll work with a 1/4" gap and if that's still not enough then the sensor could be insulated with bakelite.......maybe

i'm not saying that this is a superior system but for a 44CC twin it might be preferable to using two separate CH ignitions...it would save at least 1/2 lb. and that can make a substantial difference for a model this size.
