My Walker mower 26efi 2002 has a problem, When the motor is running for around 20 mins in cutting time the motor slow down and will not cut the lawn, so i turn off the motor for around 2 mins restart and i get the same problem in 10 mins or less. just over 2600 hours, Can anyone help me?
I have change the spark plugs, oil, fuel pump, fuel lines,

The early efi from Kohler had this problem, Dixie Chopper had a big falling out over it (and a few other issues) and dropped anything to do with efi and Kohler and now relies on Generac Motors.

If i remember right some time you can replace a sensor or two, but most the time it is the control box. Very expensive I am told.

Don't get any sensors yet take a compression text before you start the engine in the morning and one after 20 minutes of run time compere them and see if they in with factory specs. :waving:

I have the same year. Try taking off the plate in front of the rear tire, there is a sensor held on with two screws that reads of the fly wheel the fins get dirt and grass in them I just clean them off and it runs great. Or this part could be damanged from your rear tire hitting the plate. Part is cheap.
