Further comments in getting ready to tune and drive.
Proform "Mopar authorized" Ignition kit.
Not much info posted about the internals of these. So my advice is this. If its running OK, then the first opportunity measure the timing versus rpm from idle on up through 2000 rpm. Then if your comfortable doing so, maybe 2800 rpm and 3400. If not, don't sweat it. Get the lower rpm measuerments. You just want to document the baseline you've been handed.
You will need a timing light, a tachometer, and a golf tee. The tee is to plug the vacuum line to the vacuum advance.
Edelbrock carb AVS2 650 rating. with electric choke.
There are many things you can adjust or tune on this carb. At first, leave it alone if its running decently.
Sequence of importance for tuning:
Fuel level in bowl
Throttle position at slow idle (warmed up). This effects idle and off-idle
Idle mix screws. These effect idle when warmed up. Tune by turning in slowly. When rpm begins to drop, stop. Turn back rich 1/8 turn.
Jets. Wide open throttle in upper gears or other max load situations
Jets with rods. Cruising at high speed fuel mixture. (the instruction manual has charts of the various combinations effect the mixture)
Step up spring. A way of controlling when enrichment is needed.
When/If you want an explanation of how the carb works, go to the late 60s Master Tech info on carb fundementals here

If you have trouble with start up check the choke. it may be too open or too closed. Also see how it was wired in as factory did not rely on electric choke in '71. So you just want to know how the shop spliced it in.
If its running decent, I wouldn't mess with anything. Just document for future reference. After a while, remove a spark plug or two and see what they look like. Eventually if you're interested, you can begin tuning for performance. By this I mean the stuff that some people brought up earlier in the thread; timing, fuel mix at wide open throttle, fuel mix for high speed cruising, etc. If its not running decent in some situations then you will have to dive in sooner.
