Kohler PH-XT149-0225 will not stay running.

I have replaced the plug, cleaned the carb with carb cleaner (I did not soak it or take it off), made sure I had new gas, made sure the gas cap is vented, and replaced the fuel line.

It will start, run for a few seconds, then shut off.

Any ideas appreciated. Thanks!

You need to take the carburetor off and deep clean it, spray out the jets.
It's most likely a clogged jet.
