[JAGNUTS] Thanksgiving puzzle

[Dave Sebastien]

        Andrew, If you are sure that there is spark from the coil lead and 
not from the plug leads then this can only be a bad rotor, if you pull the 
rotor off and look at the bottom side you will see a black spot where the 
spark has shorted to the dist. shaft , the spark is supposed to follow the 
rotor as it rotates and contact each pin inside the cap, from there along 
the lead to each plug individually in time.  Dave
