Regarding spark plugs fouling with carbon chunks. When I was a kid I had
an 80 Yamaha motorcycle, oil injected, single cylinder. It was notorious for fouling
the plug. I’d be cruising along and it would start spitting and sputtering,
and most times quit all together. "Some" times it would spit and sputter
until almost stopped, then let out a mighty backfire, and I’d be back
on my way. My Honda buddies didn’t have this problem 🙂
Not sure if an outboard would exhibit similar symptoms!
Prepare to be boarded!
