If you can keep the engine running by spraying starting fluid in the intake then that means its a fuel issue, have you taken the fuel line off on the carburetor and cranked the engine to see if the fuel pump is pumping out fuel? More on reddit.com

Why are Kohler Courage engines so bad?
Kohler Courage Single cylinder engines are called bucket engines for a reason. because when you're done tearing them apart to find the failure, you have a nice bucket for the parts. The issue is oil. The oil journals on those engines are undersized and vertical..and when you use old oil, contaminated oil or run them low on oil, the rod bearings quickly wear out because it can't pump the oil upward and you end up snapping either the crank or the connecting rod. They're a cool design over the Briggs singles because you can get to everything without removing the head...but I run from them anytime I see them because you never know how they were taken care of. All that aside, Kohler Magnums are great, as well as their Command series. And courage series vtwins are relatively safe also. I prefer Kohler over Briggs most of the time for twin cylinder/vtwin, and briggs over Kohler for single cylinder stuff. I flip riding mowers for a side hustle for the last 5 years. More on reddit.com

March 1, 2001 - As far as the startup, no power problem, I would ask if the engine sounds weird like air escaping when it's idling (possible blown head gasket). You should definately hear it if it is. Next how old is your machine? The early commands had ignition coil problems. Remove the blower housing and look at your coils, if they're marked MA2A or MA2B then get it to your dealer immediately, these coils have to be replaced with newer ones (Kohler will warranty it).

r/lawnmowers on Reddit: Kohler 25 hp not running properly
August 17, 2023 -
Have been having issuses with our zero turn mower motor for a bit now and can figure out whats wrong yet. We changed spark plugs, cleaned air filter and made sure oil and such where were they needed to be. We noticed gas sitting in the air box in a pool. Hired man took the carb off and cleaned it runs better BUT after it ran for about 10 mins it started smelling like gas and would blue smoke every so often. I shut it down a bit of gas was already back in the air box after cleaning. So would this be a shot float needle and seat? Its what were thinking, thoughts?

I replaced the spark plug, air filter, fuel pump, and carburetor on my engine. I also drained the old ethonal gas and have the tank half full with ethonal-free gas. The motor will not stay running. I can take the fuel pump off and pump some gas to the carb, reattach the pump and pull the chord. The motor turns over and runs for a second or 2 then shuts off. I can keep the motor running by spraying starter fluid but once I stop that, the motor dies.
I'm no small engine expert, but I feel I have everything installed correctly. Do I need to adjust a new carburetor?

If you can keep the engine running by spraying starting fluid in the intake then that means its a fuel issue, have you taken the fuel line off on the carburetor and cranked the engine to see if the fuel pump is pumping out fuel?

So if you start it when the fuel line to the carb isn’t attached, fuel flows out or no?

If your Kohler 21hp engine starts then dies, inspect the fuel solenoid. This valve controls fuel flow and may fail to open, cutting fuel supply. Test by manually activating the solenoid or bypassing it briefly.
