The spark comes from the two coils and the magnet in the flywheel. From what I gather, I think you have an oil pressure switch killing the spark. Is oil level ok in the engine? Of it is unplug the oil sending unit and see if the engine will start. If it does oil pressure switch is bad or you have low oil pressure! Timing is set by the key between the flywheel and the crankshaft and is not adjustable.
