Causes of slow spark?

AJ/FormS said

Call me a DA, but
At a cranking speed of 300 rpm, this is 5 revolution per second, and a 4-stroker fires on every second revolution so.........2.5 sparks per second on any given wire sounds normal to me,at cranking speed
Am I missing something?

That's right and it's VERY difficult.........without using a lot of battery........to judge this on a "per plug" basis

Remember this horrid thing from J.C. Whitney? Friend of mine had one. 8 wires you wrapped one around the outside of each plug wire and the neon bulbs flashed with each cylinder LMAO WHAT A RADIO NOISE GENERATOR!!!
