Hey there...Have a situation with the points on a '73 750
Norton where can jump the power from the threaded stud,at
points, to the spark plug. But when we screwed everything down
and rotated the crankshaft, when the points open there is no
spark. We lined up the marks for fully open, at which time the
other point are fully closed, and checked to make sure
everything corrisponded to the correct cylinder. At one point
we had the wire leading to one set of the points connected and
the other not and the spark transferred to the spark plug.
Then had both leads were hanging off there respective lugs,
but not screwed down, there was spark. We were encouraged; put
the screws back on, no spark. Jump the wire to the stud
individually, spark is there; just not through the actual
points; seems like something is grounding out. 

This is a brand new set of points. The others that came with
the bike started the thing.

Am a bit confused...Any ideas?

Thanks, Adam
