    I would change the spark plug boot if you’ve already checked the terminal and wire. I like to check the integrity of my boots by touching them and then grounding myself on the shroud 😆 😯 Makes you feel alive ! From what I’ve observed that when the boot looks all crackled, it leaks current. Some boots that look ok leak too.
