Ok guys here's what transpired.
  • I did end up doing the reeds completely as well as cleaning all carbs. Seeing a TINY BIT OF LIGHT is normal. The reeds never seal 100%. Obviously if one is far bent up it's bad but you will never get 0 light. I know because I put new OEM reeds in
  • All was well but I still got intermittent spark here and there. Thought it was the power pack. Replaced. Worked for awhile
  • I did all of the voltage isolation tests with a max voltage meter. All is well in isolation.
  • Realized it was a poor connection at the power pack to coil pack harness. It stick an ohm meter in the orange wires and get nothing until I wiggle.
  • I hard connected these and was fine
  • I then got one cylinder die out again (the middle one this time)
  • I did the same thing at the timer base.
  • I now have the coil packs and timer base wired with marine grade bullet connectors. These give a better connection and I can isolate each wire at a time to TSHOOT
On a 1982 motor those evinrude terminals tend to suck. Cut them and rewire yourself. That's my advice.

Old school rubber connectors have never been a problem for me unless someone left them apart and corrosion occured. Glad you found the issue and fixed it. Have fun!
