Hi guys!
Like the topic sais, what happens when a plug get`s fouled?.
Is it that the plug gets too wet and eventually the spark will jump to the side of the plug (towards the threads) instead of jumping to the electrode?.
From my own experience I know that it doesnt work to just dry it with a cloth or something, but if I use the propane heater and warm the plug intil it gets red, then it will start working again.
I`ve always wondered about this.. .

Carbon conducts electricity. The black on a fouled plug is carbon.
