Pretty easy to do with a 555 timer and a MOSFET.

That circuit is fine on any standard ignition coil. I don't see the problem.

A simpler circuit would be a relay in a multivibrator configuration but it won't work nearly as well. It takes a train of pulses to drive the coil and produce a continuous spark. Just connecting it to 12V will only produce a spark when it is disconnected.
