Any Walker mower guys on here

Ok got a 26hp EFI and it’s skipping sputtering to the point it almost useless. So replaced plugs, fuel filter, fuel pump, ran a can of seafoam thru an still skipping an sputtering... not as bad but still doing it... any ideas

Check for water in fuel.
Check ignition wires.
Check valve clearance.
Check spark at both cylinders, you may have a coil failing.

if valve clearance is off check for bent pushrods.

Hoping it’s nothing that serious... hoping O2 sensor or something else. Been reading they had some ground wire issues an to trace them all to see if that’s the problem

Coil would be my first guess.

Fuel pumps are pretty notorious for going south on those things. I see you replaced the fuel pump, so that kind of nulls that point. Did you use the correct fuel filter? I'd need more info from the machine, i.e. model and serial, to be able to help you further.

So you really have a mower with a o2 censor?
