Takeuchi TL140 fuel problem

I have a 2006 TL140 and it has a heck of a time starting, even just after shutting it down too. Compression, glow plugs, engine timing, lift pump, fuel filter, inj pump screen, fuel line from tank, and return line to tank are all in good condition. Once it's up and running it runs great, no lack of power. Takeuchi part number I1-13260-0011 is what I'm wondering if there should be some sort of a spring loaded check valve. Mine just has a little hole through the center allowing fuel to freely...
