318 Running Rough / Backfiring

Electronic ignition.

Haven't had a chance to work on it with Christmas celebrations. Also been sick all week.

Going to try and look at it again tomorrow. I'll start with plugs.

I don't know much about distributors. Would I be able to take the cap off and physically see if a weight or spring has moved or come off?

Anybody think there is a chance the torque converter is failing?
