.010 to .012"
I have a similar problem with a kawasaki mower. it was running fine, emptied the catcher and wouldn't restart. Found plug fouled, no start with a new plug. removed coil, and with an ohm meter tested continuity of poles to each other, inconclusive. found a good coil from a different B&S mower and compared readings. Kawasaki had continuity with plug lead and center pole on pick-up, B&S did not. I assume the center pole is grounding out the plug lead, so I will replace the coil and see.
For most small 4 cycle cylinder engines using a magneto and a coil to provide electricity to feed the spark the gap is .006 to .010.
Around 15,000 to 20,000 in the secondary windings of the ignition coil on most modern lawn mower engines. Alternator voltage varies with size of stator, from 2 to 40 VAC.
To test the ignition coil of a Kawasaki Rouser 135, you can use a multimeter to check the resistance between the primary and secondary windings. Compare the reading to the manufacturer's specifications to determine if the ignition coil is functioning correctly. You can also visually inspect the coil for any physical damage like cracks or corrosion.
Symptoms of a bad ignition coil on a lawn mower include difficulty starting the engine, engine misfiring or stalling, and poor performance or loss of power while mowing.
To troubleshoot a faulty lawn mower ignition coil, first check for loose or damaged connections. Next, test the coil with a multimeter to see if it is producing the correct amount of electrical resistance. If the coil is not functioning properly, it may need to be replaced.
The gap should be between .006 and .010 if it has aluminum clylinders. The gap should be between .010 and .014 if it has cast iron cylinders.
To properly maintain the ignition coil on your lawn mower for optimal performance, regularly check for any signs of wear or damage, clean the coil and surrounding area to prevent debris buildup, and ensure proper connections and grounding. Additionally, follow the manufacturer's guidelines for maintenance and replacement intervals to keep the ignition coil in good condition.
The kill wire from the coil typically connects to the ignition switch or a safety mechanism that grounds the ignition system to shut down the engine. This connection enables you to stop the mower engine by turning off the switch or engaging the safety feature.
No, there is no coil or Spark Plugs. Ignition takes place due to heating from compression of the fuel/air mixture. Some diesel engines have a "Glow Plug" for aid to starting in very cold weather.
More than likely it is a bad ignition coil.
well you first need to tell someone is it electronic ignition or dose it have points ??
