Ed,
If one plug was soaked with gas, it most likely wasn't firing for some reason. And if the engine bogged down when you stepped on the gas, you could have a carb problem. Especially if it does have a wild cam. Try to find out as much about the cam as you can, as that could lead to problems later on. Also the cylinder with the gas soaked plug could be where the gas got into your
oil pan from. If the plug isn't firing, then the gas that went to that cylinder has to go somewhere. I would first make sure that there is fire from the distributor to that cylinder. Check the plug wire and the distributor cap inside terminal that feeds juice to that cylinder. If you have a good spark through the wire then try replacing the plug anbd see what happens. If the carb has set for a long time and the guy you got it from said it needs to be replaced, that may be a good place to start. Until you get this straightened out, I wouldn't worry about replacing the fuel pump.
