My 1985 Yamaha ETXK 200 is getting intermittent power to the top left coil. (top R if your in boat facing engine) Wont fire at all when Idling down the "ICW" once she kicks in powering up on a plane, it catches n fires, trim up 1/4 the little Chapparal 198 CC shes attached to, really flys! 50mph...
