I have a conventional combustion spud gun with a 4"x 12' chamber. I have two pairs of screws inserted (one pair in the middle and one toward the clean out trap) so that I can use two sparks to ignite my fuel. I am using a battery powered BBQ ignitor. At present, I can only get one of the screw pairs to spark.
Anyone have any ideas on how I can wire both so they spark together?
Thanks.
