The float bowl on my carb isn't getting fuel. I get gas up to the fuel pump. but not into the float bowl. I've replaced the diaphram. I fill the float bowl up and it runs perfect after it uses the gas it just dies again. WHAT IS GOING ON!?

Without looking at the parts lookup, I am assuming this the engine with the fuel pump mounted on the front of the carb. Is so, remove the top of the carb, and crank the engine and see if the fuel pump is actually pumping fuel. If it is pumping then there is a blockage between the pump, through the fuel passage, and the needle valve.

yes its that engine. Ok if lets say the fuel pump wasn't pumping. How do I fix it

Other than the diaphragms, The three bolt pump has two tiny little springs that help assist the little reed flaps on the diaphragm to close, Sometimes one of those springs will get hooked on the flap preventing it from closing. that could be the issue. the four bolt pump, the reed valves are built into the center section of the pump, and are not serviceable other than replacing that part of the pump.

its the 3 bolt i replaced the diaphragms and the springs came with the kit. this lawn mower is driving me INSANE

sometimes the little spring will get hooked on the reed flap preventing it from sealing.
