have purchased 2 pumps and installed new diaphragm and gaskets as manual shows. Finally purchased on of the round plastic pumps that are used on B&S engines and I think that it is going to work. Will know more tomorrow.
got this engine running. the round fuel pump worked. took the old fuel pump off and just used the cover to close up the front so gas would pump into carb. j-b welded the vent holes closed in the cover. runs good now.:smile:
