    It was PAR, I had rebuilt the carb several years ago with a new needle & seat. I did disassemble the pump and inspect. There really wasn't any noticeable junk in there. The diaphragm itself though did appear to be swollen inside the diameter of the pump housing. As I didn't take apart the new one prior to installing, I didn't have anything to compare it to. Should the diaphragm be one constant thickness from the center out to the edge?
