Fuel System Problems in Kohler Engines Lawn Mowers

One of the most common reasons for your Kohler engine to stall after starting is fuel-related issues. This could be caused by:

a. Clogged Fuel Filter

A clogged fuel filter restricts the flow of fuel to the engine, leading to stalling. Check and replace the filter if necessary.

b. Dirty Carburetor

A carburetor clogged with dirt or debris can disrupt the fuel-air mixture, causing the engine to stall.

Ignition System Issues in Kohler Engines

If the fuel system checks out, it’s time to examine the ignition system. Problems in this area can result in a running engine that suddenly dies. Look for:

a. Faulty Spark Plug:

A damaged or fouled spark plug can lead to intermittent engine operation. Inspect and replace the spark plug as needed.

b. Ignition Coil Problems:

The ignition coil plays a crucial role in delivering sparks to the spark plug. A malfunctioning coil can cause intermittent stalling.

Troubleshooting Steps – Addressing the Issue

Now that you have a general idea of what might be causing your Kohler engine to run and then die, let’s go through some systematic troubleshooting steps.

Step 1: Inspect the Fuel System
