I'm working on a 1975 6hp Johnson. I pulled the flywheel yesterday night, and checked the coils since i had been running on one cylinder my last time out. I didn't seem to see any problems with the coils, no cracks. One coil had burn marks on it from where the ground wire coming off of the coil, was touching it, and some other small brown burn marks. Is that what happens when i a coil goes bad? Thanks in advance!

Swap coils and see if the problem follows....
