As not to waste time time and know where you are, take a compression test first.
Then , before spending $ on points/cond, I would recommend converting it to electronic ign. Short $$ and a big improvement.
I like the Crane units. The idea is get rid of the points.
These are mechanical FI cars and can not be made to run well without dead on ignition. [ no feed-back between the systems].
From there you can go down the line with diagnosis, [ wires, plugs, fuel, etc], but that is a good start and the weak link in the ignition system.
