Pulling my hair out... Had it running, though it would only rev to 2000 rpm. Swapped out the other 2 electrolyte caps, pulled off the cap and saw the rotor was cracked (guess I didn't seat it fully), replaced it.
Now it's acting like the timing is 180 off, it's simply belching fire out the exhaust... I'm sure it's something simple, but very frustrating. I'll mess with it more tomorrow. For now, I guess I'll research the wiring diagrams.

This little truck will run yet...
