not necessarily a more powerfull spark will ignite the fuel better than a weak spark

i know a spark plug doesnt produce its own voltage but if a spark plug were conected into a circuit with an ignition coil it would produce the same high voltage spark used in a car engine which would ignite the fuel better that a bbq lighter

what it the best ignition system. every one talks about using a barbique lighter, wouldnt a spark plug from a car work better?

iv bin looking around and i see most people use gas and liqiud fuels has anyone tried using a solid fuel (like gunpowder or a mixture of diesel and fertalizer), or can anyone tell me y i wont work.
