Sorry my explanation skills are lacking i know.
Ok
Sometimes the quad cranks and runs fine. Either it will die out on me or wont start running off the back. When it does not run, the the Oil light blinks, the engine will turn over, but does not get any spark from the plug to run. The oil is not hot the quad most times, has not even run yet, or not for long at all. Oil is filled correctly. New filter, changed it again. Turned the engine over with the filter out, and it sprays oil from the oil filter passage all over my shop. I am confident it is getting oil. I am almost positive it has nothing to do with oil at all. Believe it is some type of electrical problem. I have looked for bare wires, corroded connectors, nothing found. All the fenders off the quad, so i can see everything well. Kinda at a dead end, my trouble shooting skills on these small engines are like my explanations skills, lacking. Thanks in advance for any help can be given.
