I have a 1982 200 that eats spark plugs. The plugs are never fouled, they just stop working. The engine runs fine when a new plug is in, although it runs a little rich at idle. The carb has been taken down and cleaned numerous times, and the float adjusted. The plug usually lasts only a day or so before they go out. They seem to be shorting out or something. Can someone offer any suggestions?
