eons ago when I fucked around with N/A Peripheral Ports, inductive ignitions were the way to solve all the hassels with firing plugs, it was straight out of the Mazda factory racing hand book, however I was a broke ass like BDC and could not afford shit so inductive it was, and had similar nightmares like this bloke. < (well boxes of spark plugs changes anyway)
Inductive is garbage, always has been on rotaries always will be.
Man Up and get a CDI system, you will long forget needing to change plugs (hot warm up) cold racing lol! one plug does ALL! and you never ever need to worry about fouling, CDI gets through ground shunts with ease, does not care about fouled plugs so it is made for very low air speed poor fuel mixing Peripheral Ports are natorious for.
Leave inductive ignitions for the rookies and ass hat tuners.
