So i just hooked up my new lightening CDI and it started up first try. I was letting it warm up and all was going well. After about 2 min the rpm shot up and the engine started smoking. I hit the kill switch and nothing. So i disconnected the Spark plug wire from the engine, still kept running. Next, in a panic, i disconnected CDI wires from the motor and it still kept running. I had to choke it out to get the engine to cut off. Any ideas on what happened and how to fix it?
