Benno...I can remember in my 'apprentice days', being handed an order for 'minor tune up', discovering carbon tracking in a dist cap, no crack... Further inspection dictated a low (or dead) cylinder at the end of that wire... As should have been done in the first place, tune ups got compression tested from then on...Had an old Mercedes with a burned valve, actually 'torched' the lug thru the cap! High voltage without due pressure can do straaaange things... AGREE in SPADES on the right number of contacts/wires to relative cylinder count. (unless there are 'twin plug' cylinders)
Well that is an acceptable explanation. I think that I have spent too much time around motor cycles. It is easy to come up with something that will work and not have to pay out the nose for a part that is not going to be utilized.
