Well, here is what I think. I would probably question anyones intelligence who uses the word "Dumbo". I also would question anyone who would destroy something that they did not understand. You probably do not know where to set the timing on that particular system, since that information is not available. You must determine if the system retards the timing for start up, or if the system advances the timing after startup, depending on rpm. It could be either, and you would never know. The supplier doesnt know, the manf. doesnt know. That information has to be acquired by deduction which requires logical thinking. Logical thinking does not go hand in hand with "hammering"
