Ok so I bought a new cylinder, new coil, and new recoil for my tri zinger but still no spark. I tested the tether kill and it works then I was just looking at the wiring diagram and found out there is supposed to be an engine speed controller. that would explain the extra wiring harness and the black and white wire I have that don't go to anything. my question is :Would that cause my spark issue being that it is missing?
