Default Re: 4 Blackened Spark Plugs?

Many years ago I picked up a set of spark plugs at NAPA for our 1929. The counterman didn’t give me the correct plugs. They looked and fitted fine but they fouled within just a few miles. Not knowing my new plugs were the problem, I checked everything.

Finally went back and got a set of Champions W16. Has been running great every since.
