Working on a motor for a friend. His 20 hp Mariner had no fire. He said the switchbox had been replaced last year. I cleaned every connection I could find, disconnected the kill switch, and could never get any fire so I ordered a new switchbox and installed it. Now I have spark jumping 7/16 on one cylinder. To test and see if it was a coil issue I swapped the leads to opposite coils and the spark moved to the other cylinder. I have reached the end of my knowledge. What do I need to do?
