For your consideration is an original Associated or United 1-1/2hp Johnny Boy Water cooler or Busy Boy air cooled cylinder Head for a Hit Miss Stationary Engine. This has brand new valves included with it. There is 1 new valve spring retainer included that still needs machined, the used one needs the center enlarged as it appears to have had larger valve stems installed. The raised part of BFB head for the cylinder bore appears to be 3-5/8″, the bolt pattern appears to be 4-1/2″ on center. The rocker stand has been repaired as can be seen in the pics. It’s been painted silver. The exhaust threads appears to be good.
