      I picked up a 5 hp Atlas and a 3.6 hp Firestone outboard at a motorcycle swap meet about a month ago.  The Atlas is in great shape.  Not sure it has ever been used much.  checked it out and it fired right up.  The Firestone is a little rough but is all there, has good compression and spark. Does anyone have a number for the correct spark plug.  The Firestone is from 1953.  Any help would be appreciated.
