So this was my first weekend out in the driveway working on my first ever project car. 'Bout damn time...a middle age man just picking up a wrench now. Guess better late than never. 
Anyhow, I've gotten great support from the Fiat forums, which has been awesome.
Taking it one step at a time. The car I'm working on hasn't started in about 7 years. So I'm just doing some very basics. Put a new battery in it, pulled the plugs and dropped a little ATF in the cylinders, pulled the air cleaner to check the carb, turned the motor by hand to make sure it wasn't seized. After all that, I was able to crank the motor with the starter. The engine turned over real nice, which is encouraging. Next step is to drop a bit of fuel in the carb to see if it'll actually start.
Thought I'd post a question here. When I pulled the plugs, 3 of the 4 looked real clean. The other plug, in cylinder 2, was dark. Curious what the thoughts are for the cause of having one dirty plug? Could it be oil? Here's a picture of one of the clean plugs next to the dirty one.
That's a 7 year old plug? I'm not sure how much useful info you'll be getting from it.
Is the black stuff moist at all? Could be a bad tube seal, letting oil on the plug. Or it could be remnants of the motor running rich 7 years ago. 
Yeah, those were the plugs I pulled out of the car. The PO said it had last been run about 7 years ago. The black stuff was dry. Kinda figured it may not mean much, but thought I'd ask. Just found it strange only one plug looked like that, the other three were clean.
When I read the plug on my 2-stroke four wheeler the best way to get a reading was to run full blast and then shut down the engine and coast to a stop.
White - Lean, Tan - Perfect, Black/Wet - Rich
You can delve waaaayyyy deeper into it than that, but it'll get ya started.
Also you could be looking at a bad ring in that cylinder, but you'll never really know until you fire her up on new plugs. Then show us the pics of what THOSE plugs look like.
Looks like it's run a little rich on that cylinder. I wouldn't worry for the time being, stick new plugs in and check back once you've been able to run the engine properly.
