You Seafoamed through the carb then changed the plugs right away? If so there is a very good chance you changed how the plugs should look. Is there a problem with the way the engine runs?
basically, the vehicle was rolled offroad and lost about 1 quart oil trhur the filler cap/pvc and manifold. The intake was sefoamed to remove oil that got into the intake manifold. the oil was also changed
Runs Ok, was wondering why #3 would be so different and the significance of the fuel odor in one clynider. what would cause that? bad injector?
