Timing way off..help.

Only with a light..was brighter on one side than other..if I jump a jumper from positive battery to positive coil and she Sparks what..then?? Thanks for help beast!!

That would mean the coil isn't getting the power it needs, and the ignition system has a problem somewhere loosing voltage. (switch, wires, ballast, plugs where wires connect)
It could be an electrical issue instead of a part.
