0DGW 11 months ago OMG, the guy is asking for some Ohmmeter readings of the coil. He knows how to test for spark. Here is what I see on my Homelite 26cc weed wacker which is about 12 years old. From the spark plug high voltage wire (high side of the secondary winding) to ground (engine block) I get 3.84K Ohms. From the kill switch high side wire (which I am guessing is the high side of the primary coil winding) to ground is 348 Ohms. I do have a blue-white spark that I could not see in sunlight but taking it indoors made it visible. Any Ohm readings similar to these should be fine.
