Once again, the spark you see when you crank the engine can be completely different from what is going on in the combustion chambers, it takes more energy to fire those plugs in the engine while it is running, and heat can also cause spark break down.
Go ahead and pull the flywheel inspection cover to have a peak, but please don’t forget to just try the engine with new plugs!
