Introduction to Kohler Engines

Kohler engines are a popular brand of engine used in a variety of applications. Kohler engines are known for their reliability and quality, from lawnmowers to generators.

But even the best engine can experience problems. If your Kohler engine is not starting, one of the possible causes is that it’s not getting sparked. InThisrtic will walk you through troubleshooting and fixing a Kohler engine that needs to be sparked.

Common Causes of a No Spark Issue

There are a few common causes of a no-spark issue. The first is an ignition module problem. This common issue can be fixed by replacing the ignition module.

Another common cause of a no-spark issue is an issue with the wiring. If the wiring is not connected properly or is damaged, it can prevent the engine from sparking.

Finally, the most common cause of a no-spark issue is a problem with the spark plugs. If the spark plugs are not firing correctly, it will prevent the engine from sparking.

Checking the Spark Plug

Before you do anything else, you should check the spark plug. This is the easiest and most effective way to troubleshoot any problems with the ignition system.

If the spark plug is dirty, it can cause problems with the engine’s ability to produce a spark. If it’s damaged or worn out, it won’t be able to do its job properly. So, make sure to clean or replace the spark plug if necessary.

Testing the Ignition Coil

If all the other parts of your engine are in good condition, then it may be time to test the ignition coil on your Kohler engine. The first step is disconnecting the ignition wires from the spark plug and turning on the ignition switch. The next step is to check if any spark is coming from the coil connection when the switch is turned on.

You can do this by attaching a spark tester to the coil and grounding it against a metal surface like the engine block. 

If there’s no spark, that could indicate that you need to replace the ignition coil. It’s also important to check for corrosion or burn marks around where the wires attach, as this could also be a sign of an issue with the coils or wiring.

If you’re still having issues after testing for ignition, you can check for voltage at different points in your engine’s electrical system by using a multimeter. This can help narrow down any other potential issues and make troubleshooting more efficient.

Ignition Timing and Troubleshooting

If your Kohler engine isn’t sparking, then it’s likely due to a problem with the ignition timing. This process sets up when spark plugs are fired, and fuel injectors are opened.

To check your engine’s ignition timing, you’ll need a timing light which is a device that connects to your spark plug wire and measures the rotational speed of the crankshaft and piston movement. 

If you don’t have one available, there are other methods of troubleshooting ignition timing problems, like checking for spark at the spark plug and inspecting for vacuum leaks in the carburetor.

If you don’t properly adjust the ignition timing on your Kohler engine, you may experience misfires or a decrease in performance.
