Odd Starting Problem on Kohler engine
Craftsman 917-271131, CV16s Kohler engine. Last several weeks, mower has died and needed to cool down a bit before it would re-start, then finally, no start at all. Using an ignition coil test light, I could see there was not spark. Assumed (I know, stupid) it was the ignition coil, as it looked pretty old, so I replaced it. Still no spark. Shined up the magnets on the flywheel, cleaned contacts on coil wires, still no spark. Then, with the cowl off, I was inspecting the coil wires for breaks. I hit the start key, and it started! Problem was, I had forgotten to reconnect the coil wires! By process of elimination, I have found that if I leave the yellow wire that comes from the Spark Advance Module off of the coil, the engine will start. Does anyone have an explanation for this?
