Broken spark plug
Anybody know what would cause the center electrode insulator to break up? I have had this problem twice now, on the number one cylinder only, and it causes a cold miss and an occasional backfire through the carb until it warms up, then is mostly smoothes out. It's an inline six. Any info/suggestions would be greatly appreciated.
