I have a Gravely ZT 2148 w/Kohler Command V-Twin model CV23. I have
recently serviced with new air/oil filter along with oil change. The motor
turns over but does not run. It will run by pouring fuel into carb. The
clear fuel filter shows no fuel being drawn into it while cranking. I
replaced fuel pump with new and it started to work properly and ran fine.
I mowed my yard and engine suddenly died. I inspected fuel filter and
there was no gas although gas in tank. I pulled pickup tube and checked
screen which is fine. Mower will run if I pour gas in carb. During
cranking there is no gas being drawn into fuel filter. I also have a lot
of oil coming from PVC where inserts into valve cover. I replaced the
grommet with a new one and it is already torn. Could my crankcase breather
be clogged? I removed my oil fill cap and cranked and there is a lot of
oil shooting out????

You could have some foreign material,such as grass,bug or rust in the
gas tank preventing the gas getting to to the filter. Take the hose off
the bottom of the tank and see if you get gas there.
