Here you see the taps in the middle of the cross wires, NC Negative and NO positive on the end.

I think only one diode may be needed. With one diode alone the kickback is awesome. I believe it must be returning %100 of the IK and BEMF from both pulses. It's really hot. Nice size jumping blue flyback spark. I need to get it on a scope. One thing for sure, it's definitely a "Flyback Booster" design. I'm waiting on an order of super capacitors from China. There's a chance this newly improved model may self run. I interspersed the Neo discs with steel hex nuts to. lengthen the piston and it has added force to the motor. The setup allows me to position the tubes with screw collars so there' a space between the middle; The tubes are held together by an elastic band and pressed up against the coil face by the screw collars for peak rev up. This way I can narrow or widen the distance between the switch contacts with small adjustments of the screw collars. It's running very strong and dependable self starting. This design is a "State of the Art" leader.

Here's a short video showing the "Self Starting" feature:
