Replaced plugs. I also have extras that I can plug into a lead to check
the intensity of a spark at the end of the plug wire itself.

Double checked and confirmed it's hooked up correctly. Even took a

Money's tight right now, but I know how tempting it is to do exactly
that.
So I used used parts from my stock pile of components, but test each one
before installation. Some items like cap and rotor had less than 10
minutes running time on them on a previous engine so they are doing well.
My next step is to confirm the timing is set correctly- it's always
possible something got bumped and it's now off on the distributor.
