It's the coil, you need the E-Coil to get it to work right.
E-Coil = High Energy Coil 40,000 to 60,000 volts.

Follow the wiring diagram to do the wiring Correct.

Horse ****. While "some" coils might cause a problem, you don't HAVE to have an E coil to make the thing run and run well. That said, yes, the type of coil might somehow denegrate "ultimate" spark power output
