Here a strange one (I think). Fresh dist., carb rebuilt, new plug wires, clear fuel in glass fuel bowl, plugs have been cleaned. Starts and runs great up to 75 mph, for about 10 miles. Develops a bad miss. Pull plugs and the outer ones at all four corners are black and sooty. The ones in the middle of both banks are a nice brown. Remember it's a 12 cylinder. What do you think guys, gals and Hotrod Lincoln ? Thanks
