Kawasaki mule starts and idles but won’t rev up

[JonR]

I need help! Kawasaki mule diesel starts an idles just fine, but it won’t rev up any RPMs. Blown out all the fuel lines, change the fuel filter. Ran half a can of liquid Molly diesel, purge direct into the engine to dissolve any gum up screens or anything like that. I’ve also checked and blown out all the vent lines for fuel. It seems to be starving for fuel, any ideas? What’s next?

Is there a coarse screen on the bottom in the fuel tank outlet?

Make sure it's not air starved, ck air filter.

Make sure the pedal is advancing the throttle
