Mind boggled 1966

So I'm new to the forum, not so new to impalas. I just bought a 1966 regular impala with factory ac and a 283 on Monday. I test drove the car before I bought and car drove just fine.

When I went back to the guys house to buy it, it fired up and I drove it home (30 miles away). I parked the car and started it again 15 minutes later, it stalled out, fired it up again, this time giving it a little gas and she started right up, I drove it around the block a few times and parked it.

Today it wouldn't start. When I turned the key it just kept turning, but wouldn't catch. I did some fiddling around with the carb, I could visually see gas going into the filter when my friend cranked, still nothing. I went to autozone charged the battery (they said it was good but needed a charge), bought some starter fluid, sprayed two quick shots in the carb and the car fired right up.

I took the car on a drive for about twenty minutes and it ran fine, it felt a little different but I figured I must've tweaked the carb by accident a little, so I would just adjust it later. Once I returned from the drive I parked the car. Not even a minute later I figured hell let's see what happens now. I stick the key in and turn, nothing, the car literally won't do anything, it's like the batteries dead but with no clicking. The lights still come so I know there's power. I have no clue what is going on.

If you guys have any insight or thoughts I would love to hear.

Btw this car hasn't been driven much, the guy told me it has been just sitting in the driveway.

I take it back, the lights won't come on, at least now they don't. I went outside to check and they won't turn on, neither do the lights inside the headliner panels. There's no power at all now.

Just to throw it out there, I just found that the battery terminal connector on the negative side isn't quite catching on the post.no matter how hard I crank it on it still wiggles. I'm pretty sure that's the culprit. I can swap them out tomorrow but I fear that's not the entire issue at hand.

After I read your first post, I was just going to say "check your Battery Terminals".

Replace them if necessary.

Had a similar issue that it was hard to start the car when cold and after driving, in my case it was a leaking float in the carb which was flooding the carburetor.
When you keep cranking is there fuel coming out of the tail pipes or on top of the manifold?

I'm not sure, I'm gonna swap out the battery terminal post and connectors today. When I get it fired up again I'll check. I did discover that the bolt that secures the air cleaner to the carb was threaded so low that it actually was touching the choke plate, disabling it from closing all the way. I wasn't sure if that was normal or not. A guy on this site told me no it was not. I will take care of that as well and see what happens.

Put a can of Berrymans B12 carb cleaner in your tank as you probably have some water in there after sitting outside.

I will give that a shot. I slapped some new connectors and a terminal shim on the battery today and the car fired right up. I still the think the carb needs some tuning or cleaning though. The negative cable wasn't attaching correctly. I kinda wonder if that was my issue the entire time (start up issue), that it just wasn't getting enough current.
