The ignition coil sends the electric current to the spark plug at the proper time to ignite the fuel in the cylinder. Replace the ignition coil if it doesn’t send electric current to the spark plug when you pull the recoil starter rope. Let the engine cool.Click to see full answer. Beside this, how does an ignition coil work on a lawn mower?When you start your lawn mower or small engine, you turn the flywheel and its magnets pass the coil (or armature). This creates a spark. Once the engine is running, the flywheel keeps rotating, the magnets keep passing the coil and the spark plug keep firing based on a specific timing.Beside above, how do I fix no spark? If you do not see a spark, there is an ignition problem. Remove a plug wire and insert an old spark plug or a spark plug tester into the end of the wire (the plug boot). Place the spark plug on a metal surface on the engine, or ground the spark plug tester to the engine. Then crank the engine to check for a spark. One may also ask, why do lawn mower ignition coils fail? There are 3 “normal” causes for ignition coil failure. The operating temperature of the engine gets to hot and burns the coil out. This is not real common on a small engine as usually the engine will shut down from heat before the coil will fail, but it is possible. Resistance problems.What causes no spark to the spark plug?Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.
