Hi folks. I have a Honda BF40 on a work pontoon that used to run very good. ... three years ago. When I just tried to start it, it wouldn't start and gas flooded out of the carbs. Assuming it was shellac from old gas, I cleaned the carbs. After putting it back together, there is no spark from any of the three spark plugs. Not being too familiar with outboards, where do I start to look for the missing spark? Any tricks or tips would be very helpful as I'm getting ready to sell it (to move away from the water .. yuk).
