Check the pulse coil. They do fail over time.
There's something suspicious about how the wire is twisted. That's not the way electrical wire is assembled nor is it terminated in that fasion...ie extra twists. Otherwise, heat, incorrect installation of the coil or rotor..or a really bad main bearing can bring problems to the forefront.You can see the original pulse coil input wires are both cracked and I ended up with no spark...no idea what causes this, any ideas?
