Hei conversion Intermittent start?

Sorry to pile on, but you did say several times that you twisted the pickup wires, which many people suggested (one even saying that was his problem), and then your photos show totally different. Instead of just endlessly spinning the engine, backup to basics as many suggested. Remove the distributor and spin it by hand while looking for a spark across a gap you carefully arranged on the coil output wire (don't go thru the distributor cap). You have too many variables in the equation as is.
