Check all the connections to the coil and distributor. The car was running fine until it sat, I'd get some fresh gas if you haven't already and do,as Dave said and check the points.

Is the fuel level in the middle of the glass?

Sounds like the spark may be a bit weak. The dwell should be check or new points+condensor installed. or you could try filing the points lightly with a nail file

Have spark however the plugs are only putting out a light orange spark. Also, car feels like it wants to turn over now but only when I floor the throttle but it won't turn over.

If the fuel is near the center of the glass, that's good. Time to check for spark

* Pull the center wire out of the distributor cap
* Put a screwdriver into the metal end of the wire
* Place screwdriver near the strut tower bolt, with the metal of the screwdriver about 1/4" from the bolt
* Crank engine (turn key to Start) while watching. Fat blue/eyllow sparks should jump from the screwdriver to the bolt while engine is cranking. Thin yellow sparks indicate a problem
* Replace wire into distributor cap

If there is good spark, repeat the test for each of the other four distributor cap wires

* Does the center wire have good spark?
* Do the four outer wires have good spark?
* Do none of four outer wires have spark? Inspect the distributor cap & rotor

Glad to hear that the choke adjustment fixed the previous starting problem

About the new problem, to start the engine it needs fuel + spark
* look below the air cleaner to see if fuel is in the carburetor




Fuel should be near the dot. If it's way above the dot, the engine is flooded. If it's way below the dot, fuel pump hasn't drawn up the fuel

So I fixed the open choke and the car started for a few weeks. Now I can't start it again. Battery is good, starter is good and butterfly choke is closed all the way.

The car currently just cranks strongly but won't turn over. I've tried stepping on the throttle 5-10 times to get a good amount of gas in but no luck.

Check your earths too. Run the neg off the jumper cable to the engine rather than the battery terminal, try and get close to the starter on the mounting bolts if you can. You can also run the pos direct to the starter, but it is hard to get it to hold there if you dont have a helper. This eliminates any voltage drop or wiring issues.
If that doesnt work pull the starter motor and bench test it.

That's barely cranking. It won't start like that

Either the battery or the starter is bad. I would temporarily swap the battery with a known good one, say from your other car. If it cranks right over, get a new battery. If it does the same thing, replace the starter

This is a video of me trying to start my datsun while it is connected with jumper cables my other car with a good battery. It is still slow cranking and the jumper cables don't seem it help it at all. I left the cables attached for at least 10mins before I tried to start the car. http://tinypic.com/r/2vi0d2h/9

Oh yeah, electronic ignition needs more volts. If during cranking the voltage drops to 6 volts the old points will still spark, but electronic ignition will completely stop below about 7 to 11 volts. Jumper cables will work around that problem
