No gas was coming out of the hose from pump to carb. Yeah... I think this is getting above my pay grade? I am just going to assume I rebuilt the fuel pump wrong ( 3 times???) or it is defective in some way. I am going to bite the bullet and purchase a way overpriced OEM Fuel Pump and pray like heck that solves the problem. If not she goes up for sale or I will take it to a pro ( not likely).
ok first things is never give up...when reassembling these pumps mounting a few critical parts properly helps the reassembly ... mainly the springs ( big and tiny one with mushroom heads.
To make certain they do not flip over I always wet the spring base with crazy glue to hold things vertical. I also wet the spring top to glue on the mushrooms. Makes thing a lot easier to restack the parts. Orientation of the core middle plastic layer is tricky... read the document closely and always finish with a blow test . IN to OUT only to pass air !!
putting your finger on the engine side pulse openning should allow you to feel the pumping pressureas air attempts to leave the crankcase to activate the pump. it should feel rather forcefull. A bit like a finger on a spark plug hole . If not.....pressure is not building up in the crankcase on the downstrokes . Top and bottom crankcase voids are identical but separate cavities. Air should not pass between the two nor should air pressure escape from crankcase seals or reeds . Air pushed OUT of the carb is easy to test with a piece of paper or kleenex in front
I doubt it is your problem. PIA to buy a OEM pump but if it fixes it great.
Patience brings joy.
