.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.
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.
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 ??
All of the engines in a 2003 are distributorless. They are coil on plug ignition.
both the 3100 and 3800 series engines have the ignition control module mounted under the coil packs. remove the coil packs and there it is.
what are you trying to measure and with what type of meter? generally we check the module with a spark tester. if there is no spark with the spark tester we check the kill wires and any safety switches that may cause a no spark issue and if all that still shows no spark then we replace the module.
Ignition module has a coil of wire; some types of insulating materials that protects from heat damage and transistors. Ignition regulates the spark generation in internal combustion engines.
