The spark plug is a champion RDJ8J or equivalent brand. The fuel oil mix 40:1 is using McCulloch oil.
As to the carby it could be either a walbro or Zama type but usually the fuel line from the tank that has the filter on it goes directly to the carby and the other one from the carby goes to the primer and then back to the tank.
