If the carburetor is clogged, try cleaning it with carburetor cleaner. If cleaning the carburetor isn’t effective, rebuild or replace the entire carburetor. The ignition coil sends voltage to the spark plug while the engine is running. If the ignition coil is defective, the engine may not start.
Why does my Kohler engine keep shutting off?
The carburetor might be clogged. A clogged carburetor is most commonly caused by leaving fuel in the engine for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the engine to stall.

What indicates a dead ignition coil?
If your engine misfires or stalls when you are idle or when you stop suddenly or accelerate, there could be a problem with your ignition coil. A misfire — which can sound like a coughing or sputtering noise or feel like a jerk or strong vibration — means that one of the engine’s cylinders is not firing correctly.
How many ohms should a ignition coil read?
The ohmic resistance of the coil is around 0.2–3.0 Ω on the primary side and around 5–20 kΩ on the secondary side. The winding ratio of primary to secondary winding is 1:100. The technical structure may vary depending on the ignition coil’s area of application.
If there’s spark, great, it works! If there’s no spark, it’s a bad coil.
How many ohms should an ignition coil wire have?
The Society of Automotive Engineers suggests the maximum resistance should be 12,000 ohms-per-foot.
How do you test a twin cylinder coil?
How do I know if my ignition coil is internally resisted?
Using an ohmmeter, check the resistance between the side terminals of the coil. Do this with all of the wires to the coil disconnected. You should see 0.75 to 0.81 ohm of resistance. Then check the resistance between either side terminal and the center high tension terminal.
What happens if spark plug wire resistance is too low?
Lower resistance means more of the ignition coils energy is going towards bridging the gap or the spark plug. That hotter spark can create a more even burn of the fuel/air mixture in the cylinder, and thus, more power output from the engine. Also, all the shielding inside a wire is not free.
How do I know if my spark is strong enough?
The proper method to check for spark is with a spark tester. It resembles a spark plug but has a sunken center electrode that simulates a load on the coil. Holding the plug wire and seeing if a spark jumps to ground is inconclusive. The spark is arcing in atmospheric pressure.
When spark plugs are new, the resistance value is between 500 and 3000 ohms. As the plug ages, values below 5000 ohms are acceptable. But once the plug’s resistance value exceeds 5000 ohms, the plug should be replaced.
Will a hotter spark plug stop fouling?
Rich air/fuel ratios require a hotter plug to prevent fouling. Mixtures that cause the plugs to read lean might contribute to preignition or detonation.
What causes black fouled sparkplugs?
Carbon fouled
Black, dry soot on the electrodes and insulator tip indicates a carbon-fouled plug. This can be caused by a dirty air filter, excessive driving at low speeds, too rich of a fuel/air mixture or idling your vehicle for too long.
Why would you use a colder spark plug?
A colder heat range spark plug may be necessary if the ignition timing has been advanced to near the knock level. Higher cylinder temperatures near the knock level will bring the spark plug firing end temperature closer to the pre-ignition range.
What causes all spark plugs to foul quickly?
Causes of a carbon-fouled spark plug include a dirty air filter, excessive driving at low speeds, too rich of a fuel/air mixture, dirty fuel injectors or idling your vehicle for too long.
What are the two most common causes of spark plug failure?
Many factors can cause a spark plug to fail; from incorrect heat ranges to improper gapping, to chemical contamination. Yet 90% of spark plug damage claims are due to improper torque.
