Kohler Lawn Mower Engine Runs then Die

1. Kohler Engine Runs then Dies

If your mower runs and shuts off, it can be due to a few reasons. The first thing to check is the fuel flow and the condition of your spark plug. If you are having fuel flow issues, this can cause the engine to die out. If the spark plug is dirty or your plug wire is defective, you may not have a spark. Most lawn mowers that start but quickly die have unclean carburetors. Possible causes could be:

  • Bad or Old Gas

The solution is as simple as draining the gas tank and cleaning the carburetor. For the sake of your reading comfort, I have split this manual in half. The problem is usually solved by draining the gas bowl, which takes no more than five minutes.

5. Kohler Engine Keeps Shutting off

Kohler lawn mower engine keeps shutting off is a common lawn mower problem. Shutting down before you finish mowing can be caused by dirt, rocks, or other debris getting caught inside the engine. Dirt and dust can build up in the air filter, which is located near the air intake on the top of the engine.

If this gets clogged, it will restrict airflow to the engine and cause it to shut down before you’re done mowing.

If the engine continues to shut off, check the cleanliness of the fuel tank. Clean any debris with a vacuum cleaner, then flush the tank with fresh gas. If necessary, replace the fuel filter and clean or replace any corroded parts on the mower engine.

It’s also important to keep an eye on the oil level in your lawn mower engine. Make sure that it’s full before you start up each time you use it. It’s also important to change out your lawn mower oil every few weeks to keep your engine running smoothly.

In addition, it’s also possible for a clogged carburetor to cause this problem. When you first start your Kohler lawn mower engine is surging, don’t panic. Instead, check the fuel and oil levels in the engine. Make sure there are no leaks and that there’s enough fuel in the tank.

Clean off any debris from around it with a soft rag or brush. Make sure that there is no excess dirt on top of it and that the gap is open so that the spark can enter easily.

Run the engine at a low speed and check for power loss by pressing the accelerator pedal vigorously while shaking the mower and observing if the engine starts up smoothly or not.

You should be able to start the machine easily and see the engine light coming on or stay on constantly if the problem is an overheating engine. If the engine light does not come on, check all fuel lines and fittings for leaks.
