I dont have FB. Done away with that years ago.
Look on YouTube and it will show you how, but put simply hook a 12v+ straight to the coil, a 12v- with a normally open momentary switch. Sparkplug hooked to the coil and 12v- hooked to the metal of the plug. .
Activate the switch.
Switch closed charges the coil, release and it discharges via the plug.
