I saved on the clutch only to find the new in March fuel pump has died
. The original had replaceable check valves - if you could figure out
which ones you needed - these are molded into the plastic top section .
The outlet valve isn't closing and it's fuel starved . And that little
bastard wasn't cheap , 35 bucks plus and it fails in like 3 months .
  I briefly considered mounting an "IV bottle" to gravity feed but
that's a bit too "country" even for me .

Mine would stumble at times and catch again. Usually on HOT days and
after running the gas tank maybe to half or less (filled before
mowing). It has a Kohler Command 25hp 2-cyl on it with a Crankcase
Pulse Fuel Pump. Just put up with it for awhile but it kinda bugged me.
I ordered a cheap replacement pump and a new air filter on a hunch. The
Air Filter looked okay but had oil from the rocker cover (vapor
recovery) contaminating it. Replacing the Air Filter got rid of the
stumble, didn't need the new pump. Has been a couple years now and
hasn't happened since. The vapor recovery is a direct shot into the
intake, bypasses the Air Filter. Think it was sucking so hard on the
vapor recovery that it was messing up the amount of "pulse" available
for the fuel pump...
